Hardware Functions
- Watchdog timer frequency can be selected from fs/2
Based on the timer 0, and timer 3 output, a remote control carrier with duty
cycle of 1/2 or 1/3 can be output.
- Port 6 outputs the latched data, on the event timing of the synchronous
output signal of timer 1, 5, or 7, or of the external interrupt 2 (IRQ 2).
Output frequency can be selected from fosc/2

- Transfer clock source
fosc/2, fosc/4, fosx/16, fosc/64, fs/2, fs/4
1/2 of UART baud rate timer ( timer 5 ) output
- MSB/LSB can be selected as the first bit to be transferred. Any
transfer size from 1 to 8 bits can be selected.
- Sequence transmission, sequence reception or both are available.
Full-Duplex UART ( Baud rate timer : Timer 5 )
- Parity check, Overrun error, Framing error detection
- Transfer size 7 to 8 bits can be selected.
[Note : When Matsushita standard serial writer is used for flash memory
version, serial interface 0 is used for program transfer.]
