19 06/19/2000 GL600USB/GL600USB - a/GL600USB - b revision 1. 3 algorithm can detect any analog waveform from photo - sensor with amplitude larger than 1v. the adc is a high - speed converter. it takes less than 500ns to complete the conversion. because GL600USB is running at 3 mips for usb low speed application, only two dummy instructions should be added between write phsel to read phval. 4.5 general purpose i/o ports interface with peripherals is conducted via up to 13 gpio signals. these 13 signals are divided into two po rts: port 1 and port 2. port 1 contains five lines (port1.0 - port1.4) and port 2 contains eight lines (port2.0 - port2.7). the port 1 data register is located at data memory address 06h while the port 2 data register is located at data memory address 07h. por t 2 is a low current port with analog input capability suitable for connecting photo - sensor. port 1 is a high current port capable of led drive. each gpio line may include an internal pull - up or pull - down resistor. port 2?s internal pull - down resistor valu e can be programmed by option - code. each output drive has slew - rate control to reduce emi. please see the following table for details. driving capability pull - up resistor pull - down resistor port1.0 20 ma port1.1 20 ma port1.2 4 ma 10k w port1.3 4 ma 10k w port1.4 4 ma 10k w port2.0 4 ma 4k w /8k w /16k w /32k w [1] port2.1 4 ma 4k w /8k w /16k w /32k w port2.2 4 ma 4k w /8k w /16k w /32k w port2.3 4 ma 4k w /8k w /16k w /32k w port2.4 4 ma 4k w /8k w /16k w /32k w port2.5 4 ma 4k w /8k w /16k w /32k w port2.6 4 ma 4k w /8k w /1 6k w /32k w port2.7 4 ma 4k w /8k w /16k w /32k w note 1: the pull - down resistor can be configured as 4k w , 8k w , 16k w or 32k w by option - code. table 4 - 3 general purpose i/o port summary 4.6 timer interrupt the timer interrupt is generated when the timer register over flows from ffh to 00h. this overflow sets bit tmrof (inten<2>). the interrupt can be masked by clearing bit tmroen (inten<5>). bit tmrof must be cleared in software by the timer module interrupt service routine otherwise the timer interrupt will not be gen erated again. if prescaler is disabled, the timer register will increase every instruction cycle. if prescaler is enabled, its increment cycle depends on ps0~ps2 bits in pscon register. 4.7 usb engine the usb module contains three functional blocks: a 3.3 - vo lt regulator, a low - speed usb transceiver, and the serial interface engine (sie). the following details the function of the regulator, transceiver, and sie. 4.7.1 voltage regulator the usb data lines are required by the usb specification to have a maximum outp ut voltage between 2.8v and 3.6v. because the GL600USB is a low speed usb device, the d - lines also are required to have an
20 06/19/2000 GL600USB/GL600USB - a/GL600USB - b revision 1. 3 external 1.5 - k w pull - up resistor connected between a data line and a voltage source between 3.0 v and 3.6 v. since the power provid ed by the usb cable is specified to be between 4.4v and 5.0v, an on - chip regulator is used to drop the voltage to the appropriate level for sourcing the usb transceiver and external pull - up resistor. an output pin driven by the regulator is provided to sou rce the 1.5 - k w external resistor. 4.7.2 usb transceiver the usb transceiver provides the physical interface to the usb d+ and d - data lines. the transceiver is composed of two parts: an output driver circuit and a receiver. the usb transceiver uses a different ial output driver to driver the usb data signal onto the usb cable. the static output swing of the driver in its low state is below the v ol of 0.3v with 1.5 - k w load to 3.6v and in its high state is above the v oh of 2.8v with 15 - k w load to ground. the outpu t swings between the differential high and low state are well balanced to minimize signal skew. slew rate control on the driver is used to minimize the radiated noise and cross talk. the driver?s outputs support 3 - state operation to achieve bi - directional half - duplex operation. the driver can tolerate a voltage on the signal pins of ? 0.5v to 3.8v with respect to local ground reference without damage. the rise and fall time of the signals on this cable are greater than 75ns to keep rfi (radio frequency inte rference) emissions under fcc (federal communications commission) class b limits and less than 300ns to limit timing delays, signaling skews, and distortions. the driver reaches the specified static signal levels with smooth rise and fall times, and minima l reflections and ringing when driving the cable. this driver is used only on segments between low - speed devices and the ports to which they are connected. usb data transmission is done with differential signals. a differential input receiver is used to a ccept the usb data signal. a differential 1 on the bus is represented by d+ being at least 200mv more positive than d - as seen at the receiver, and a differential 0 is represented by d - being at least 200mv more positive than d+ as seen at the receiver. th e signal cross over point must be between 1.3v and 2.0v. the receiver features an input sensitivity of 200mv when both differential data inputs are in the range of 0.8v and 2.5v with respect to the local ground reference. this is called the common mode i nput voltage range. proper data reception also is achieved when the differential data lines are outside the common mode range. the receiver can tolerate static input voltage between ? 0.5v to 3.8v with respect to its local ground reference without damage. i n addition to the differential receiver, there is a single - ended receiver for each of the two data lines. 0.0 0.2 0.4 0.6 0.8 1.0 0.0 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2.0 2.2 2.4 2.6 2.8 3.0 3.2 common mode input voltage (volts) minimum differential sensitivity (volts) figure 4 - 3 differential input sensitivity over entire common mode range
21 06/19/2000 GL600USB/GL600USB - a/GL600USB - b revision 1. 3 the data receivers for all types of devices must be able to properly decod e the differential data in the presence of jitter. the more of the bit time that any data edge can occupy and still be decoded, the more reliable the data transfer will be. data receivers are required to decode differential data transitions that occur in a window plus and minus a nominal quarter bit time from the nominal (centered) data edge position. jitter will be caused by the delay mismatches and by mismatches in the source and destination data rates (frequencies). differential data lines paired transitions n * t period + t jr2 t period consecutive transitions n * t period + t jr1 t jr t jr1 t jr2 figure 4 - 4 receiver jitter tolerance the source of data can have some variation (jitter) in the timing of edges of the data transmitted. the time between any set of data transitions is n*t period jitter time, where n is the number of bits between the transition s and t period is defined as the actual period of the data rate. the data jitter is measured with the same capacitive load used for maximum rise and fall times and is measured at the crossover points of the data lines. for low - speed transmissions, the jitt er time for any consecutive differential data transitions must be within 25ns and within 10ns for any set of paired differential data transitions. these jitter numbers include timing variations due to differential buffer delay, rise/fall time mismatches, internal clock source jitter, noise and other random effects. the output rise time and fall time are measured between 10% and 90% of the signal. edge transition time for the rising and falling edges of low - speed signals is 75ns (minimum) into a capaciti ve load (c l ) of 50pf and 300ns (maximum) into a capacitive load of 350pf. the rising and falling edges should be transitioning (monotonic) smoothly when driving the cable to avoid excessive emi. low speed: 75ns at c l = 50pf, 300ns at c l = 350pf full speed: 4 to 20ns at c l = 50pf differential data lines 10% rise time 90% fall time t f t r 10% 90% c l c l
