(i.e., the gain will affect the of fset correction.) these registers allow the user to maximize the dynamic range achievable in the given system. the last register is the mode register. bits in this register select the sleep mode as well as options for multichip arrays and production testing. note that test and multichip options do not apply to the 8-pin packaged device. users should always write 0s into the production test and multichip control bits. 0 7 0x1f 654321 p2 mode 0 0 slp p1 p0 c1 c0 slp = sleep mode: 1 places device into sleep mode 0 places device in normal operating mode c1, c0 are reserved (should be written 0 ) p2 to p0 are factory test bits (should be written 0 ) figure 1. mode register bit assignments ams ag technical content still valid

TSL3301cl 102 1 linear optical sensor array with analog-to-digital converter taos141 ? july 2011 6 copyright 2011, taos inc. the lumenology company www.taosinc.com programming information a minimum of 5 clock cycles after the stop bit is required after any command to ensure that the internal logic actions have been completed. reset commands reset commands are used to put the TSL3301cl into a known state. ireset ? interface initialization encoding: break character (10 or more consecutive start bits, or zeros) the commands vary in length from one to three bytes. ireset initializes the internal state machine that keeps track of which command bytes have been received. this command should be first and given only once after power-up to synchronize the TSL3301cl internal command interpreter. an alternative is to issue three successive reset commands. reset ? main reset encoding: 0x1b: <0001_1011> reset resets most of the internal control logic of the TSL3301cl and any readpixel command currently in progress is aborted. reset puts the pixel integrators into the auto-zero/reset state. any values that were being held in the array?s sample/hold circuits are lost. note: the value on the sdout pin is not guaranteed from the time power is applied until 30 clocks after the first reset command is issued. pixel action commands pixel action commands allow the user to control pixel integration and reading of pixel data. startint ? start integration encoding: 0x08: <0000_1000> startint causes each pixel to leave the reset state and to start integrating light. the actual execution of startint is delayed 22 clock cycles until the pixel reset cycle has been completed. (see imaging below.) sampleint ? stop integration encoding: 0x10: <0001_0000> sampleint causes each pixel to store its integrator?s contents into a sample and hold circuit. also, the integrator is returned to the reset state. readpixel ? read pixel data encoding: 0x02: <0000_0010> readpixel causes the sampled value of each pixel to be converted to an 8-bit digital value that is clocked out on the sdout pin. the lsb is the first data bit, which is preceded by a start bit (logic 0) and followed by a stop bit (logic 1). each pixel in the device is presented on sdout starting from pixel 00 and completes with pixel 101. there is a 44-clock cycle delay from the completion of the readpixel command until the first pixel data is output. gain and offset registers are used to adjust the adc converter to maximize dynamic range and should be programmed prior to invoking the readpixel command. ams ag technical content still valid
TSL3301cl 102 1 linear optical sensor array with analog-to-digital converter taos141 ? july 2011 7 the lumenology company copyright 2011, taos inc. www.taosinc.com abortpixel ? abort pixel data read encoding: 0x19: <0001_1001> abortpixel is an optional command that stops a readpixel command during its execution. it also causes pixel integration to terminate and the device to enter the auto-zero/reset state. any values that were being held in the array?s sample/hold circuits are lost. readhold ? sample and read combination encoding: 0x12: <0001_0010> readhold is a macro command that combines both the sampleint and readpixel commands into a single command. readholdnstart combination encoding: 0x16: <0001_0110> readhold is a macro command that combines the sampleint , readpixel, and startint commands into a single command. 22 clock cycles are necessary to complete the pixel reset cycle. register commands the register commands provide the user the capability of setting gain and offset corrections for each of the three zones of pixels. a4?a0 refer to the register address as given in table 2. regwrite ? write a gain/offset/mode register encoding (2 bytes): 0x40 : <010a4_a3a2a1a0> regwrite writes a value into either a gain, offset, or mode register. the 5-bit address of the register is encoded into the lower 5 bits of the command byte (the first byte). a second byte, which contains the data to be written, follows the command byte. regread ? read a gain/offset/mode register encoding: 0x60: <011a4_a3a2a1a0> regread reads the value previously stored in a gain, offset, or mode register. the 5-bit address of the register is encoded into the lower 5 bits of the command byte. following receipt of the regread command, the device places the contents of the selected register onto the sdout pin, lsb first. there is a 4-clock cycle delay from the completion of the regread command until the register contents are output. ams ag technical content still valid
TSL3301cl 102 1 linear optical sensor array with analog-to-digital converter taos141 ? july 2011 8 copyright 2011, taos inc. the lumenology company www.taosinc.com operation initialization sequence after powering on the device, a minimum of 10 clocks with sdin held high must be received by the TSL3301cl to clear the receiver logic so that a start bit will be detected correctly. the control logic may then be cleared by either issuing an ireset command (break character) or 3 reset (0x1b) commands. an additional 30 clocks must be received by the device to assure the state of sdout. sleep mode the device can be put into a power down or sleep mode by writing a 0x10 to the mode register. this turns off all the analog circuitry on the chip. normal operation is restored by writing a 0x00 to the mode register. the analog circuitry will require a minimum of 1 millisecond to recover from the sleep mode. ? note that putting the device in the sleep mode does not affect the logic states of the machine. if, for example, a readpixel command is issued, the device will respond but the resulting data will be meaningless. also note that 0x00 and 0x10 are the only two legitimate user programmable values for the single-chip version of the TSL3301cl. other values may put the device into a non-operational mode. ? for minimum sleep mode current consumption, voltage levels on logic inputs must be at either v dd or ground. imaging after powering up the device and completing the initialization sequence, it is necessary to allow a minimum of 1 millisecond for the internal analog circuitry to settle. this delay is also required when coming out of the sleep mode. issuing a starint (0x08) command will release the pixel integrators from the reset state. after an appropriate delay to integrate the i mage, the pixel data may be sampled by issuing a sampleint (0x10) command and then read out by issuing a readpixel (0x02) command. a startint command can be issued anytime after the sampleint command is issued to start another cycle. thus, it is possible to be reading out one sample while integrating the next. however, the sampled data from the previous sampleint must be completely read out before the next sampleint command is issued. the compound commands readhold (0x12) and readholdnstart ((0x16) are shortcut commands to simplify the imaging sequence. it is important to note that a pixel reset sequence is initiated with the receipt of a startint or readholdnstart command. the next integration sequence cannot start until the pixel reset sequence has been completed, which requires 22 clocks after the receipt of one of these commands. these clocks can also be used to clock commands or data into or out of the device. ams ag technical content still valid
