Panasonic MN101C77C, F77G user manual Watchdog timer, Remote control output, Buzzer output

Chapter 1 Overview

Watchdog timer

- Watchdog timer frequency can be selected from fs/216, fs/218 or fs/220.

Remote control output

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.

Synchronous output

Timer synchronous output, Interrupt synchronous 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).

Buzzer output	Output frequency can be selected from fosc/29, fosc/210, fosc/211,
	fosc/212, fosc/213, fosc/214, fx/23, fx/24.

Automatic transfer controller (ATC)

Data in the whole memory space (256 KB) can be transferred.

-External interrupt start / internal event start / software start

-Max. 255 bytes continuous transfer

-Support serial interface sequence transmission / reception

-Burst transfer ( interrupt shutdown is built-in )

A/D converter	10 bits X 7 channels input
D/A converter	8 bits X 2 channels input
Serial interface	4 types

Serial interface 0 (Full-Duplex UART / Synchronous serial interface )

❑Synchronous serial interface

-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.]
