m pd705102 9 data sheet u13675ej2v1ds00 2. internal units (1) bus control unit (bcu) controls the address bus, data bus, and control bus pins. the major functions of bcu are as follows: (a) bus arbitration arbitrates the bus mastership among bus masters (cpu, sdramc, dmac, and external bus masters). the bus mastership can be changed after completion of the bus cycle under execution, and in an idle state. (b) wait control controls eight areas in the 16-mbyte space corresponding to eight chip select signals (cs0 through cs7). generates chip select signals, controls wait states, and selects the type of bus cycle. (c) sdram controller generates commands and controls access to sdram. cas latency is 2 only. (d) rom controller accessing rom with page access function is supported. the bus cycle immediately before and addresses are compared, and wait states are controlled in the normal access (off-page) or page access (on-page) modes. a page width of 8 bytes to 16 bytes can be supported. (2) interrupt controller (icu) services maskable interrupt requests (intp00 through intp03, and intp10 through intp13) from internal peripheral hardware and external sources. the priorities of these interrupt requests can be specified in units of four groups, and edge-triggered or level-triggered interrupts can be nested. (3) dma controller (dmac) transfers data between memory and i/o in place of cpu. the transfer type is 2-cycle transfer. two transfer modes, single transfer and demand transfer, are available. (4) serial interface (uart/csi/brg) one asynchronous serial interface (uart) channel and one clocked serial interface (csi) channel is provided. as the serial clock source, the output of the baud rate generator (brg) and the bus clock can be selected. (5) real-time pulse unit (rpu) provides timer/counter functions. the on-chip 16-bit timer/event counter and 16-bit interval timer can be used to calculate pulse intervals and frequencies, and to output programmable pulses. (6) clock generator (cg) a frequency six or eight times higher than that of the resonator connected to the x1 and x2 pins is supplied as the operating clock of the cpu. in addition, both a bus clock, which functions as the operating clock of the peripheral units, and sdclkout, which functions as an operating clock, are supplied from the clkout pin. an external clock can be also input instead of connecting a resonator. for reducing the power consumption, the function switching the frequencies of the cpu clock and bus clock with power management control (pmc) is provided.
m pd705102 data sheet u13675ej2v1ds00 10 (7) port (pio) provides port functions. twenty-one i/o ports are available. the pins of these ports can be used as port pins or other function pins. (8) system control unit (syu) a circuit that eliminates noise on the reset signal (input)/nmi signal (input) is provided. (9) debug control unit (dcu) a circuit to realize mapping and trace functions is provided to implement basic debugging functions.

(2) standby mode the following two standby modes can be used. ? halt mode in this mode, the clock generator (oscillator and pll synthesizer) operates, but the operating clock of the cpu is stopped. the other internal peripheral functions are supplied with the clock and continue operation. by using this mode in combination with the normal mode, the power consumption of the entire system can be reduced. ? stop mode this mode stops supply of the clock to the cpu and peripheral i/o. it can reduce the power consumption much more than the halt mode. clock output of pll synthesizer ? in pll mode: operation of the pll can be started or stopped by the pllss bit of the power management register (pmr). ? in direct mode: the pll always stops. table 13-1 shows the operation of the clock generator in each mode.

m pd705102 data sheet u13675ej2v1ds00 78 notes for cmos devices 1 precaution against esd for semiconductors note: strong electric field, when exposed to a mos device, can cause destruction of the gate oxide and ultimately degrade the device operation. steps must be taken to stop generation of static electricity as much as possible, and quickly dissipate it once, when it has occurred. environmental control must be adequate. when it is dry, humidifier should be used. it is recommended to avoid using insulators that easily build static electricity. semiconductor devices must be stored and transported in an anti-static container, static shielding bag or conductive material. all test and measurement tools including work bench and floor should be grounded. the operator should be grounded using wrist strap. semiconductor devices must not be touched with bare hands. similar precautions need to be taken for pw boards with semiconductor devices on it. 2 handling of unused input pins for cmos note: no connection for cmos device inputs can be cause of malfunction. if no connection is provided to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence causing malfunction. cmos devices behave differently than bipolar or nmos devices. input levels of cmos devices must be fixed high or low by using a pull-up or pull-down circuitry. each unused pin should be connected to v dd or gnd with a resistor, if it is considered to have a possibility of being an output pin. all handling related to the unused pins must be judged device by device and related specifications governing the devices. 3 status before initialization of mos devices note: power-on does not necessarily define initial status of mos device. production process of mos does not define the initial operation status of the device. immediately after the power source is turned on, the devices with reset function have not yet been initialized. hence, power-on does not guarantee out-pin levels, i/o settings or contents of registers. device is not initialized until the reset signal is received. reset operation must be executed immediately after power-on for devices having reset function.
