Features (Continued)

Timer 3 - 8-bit timer

Square wave output, Event count, Cascade connection to timer 2

Clock source: fosc, fosc/4, fosc/16, fosc/64, fosc/128, fs/2, fs/8, fx, external clock

Timer 6 - 8-bit timer

One minute meter is available when combined with the timer base timer.

Timer 7 - 16-bit timer (Double buffer composition)

Square wave output and PWM output (Duty/Cycle continuous changeable) can be output to the large current pin, P53 (TM7O).

Event count, Pulse width measurement, Input capture, Remote control carrier output

Clock source: 1/1, 1/2, 1/4 or 1/16 of fosc, fs or external clock.

Timer base timer

Clock source: fosc, fx

Watchdog timer



Buzzer output, Inverted Buzzer output:



Remote control carrier output:

Based on timer 0 and timer 7 output, a remote control carrier with duty cycle of 1/2 or 1/3 can be output.



Clock output:

Fosc output or fs output is available.



Serial Interface: 2 channels

Serial interface 0 : 3 channel type synchronous / Full duplex UART

Transfer clock: fosc/2, fosc/4, fosc/16, fosc/64, fs/2, fs/4, timer 1 (or timer 2) output, timer 2 output/2, timer 2 output/8

At UART, timer 1 (or timer 2) is used as a baud rate timer

MSB/LSB can be selected as the first bit to be transferred.

Any transfer size from 1 to 8 bits can be selected.

Parity check, parity addition, overrun and framing error detection.

Usable as 2 channel type serial interface.

Serial 0 I/O (SBO0, SBI0, SBT0) can be switched to either P10 to P12 or P43 to P45.

Serial interface 3 : 3 channel type synchronous / Single Master IIC Interface

IIC communication for single master (9-bit transfer)

Transfer clock: fosc/2, fosc/4, fosc/16, fosc/64, fs/2, fs/4, timer 1 (or timer 2) output

MSB/LSB can be selected as the first bit to be transferred.

Any transfer size from 1 to 8 bits can be selected.
