Timer A: 8-bit timer
Count-up timer with selection of eight internal clock signals divided from the
system clock (φ) * and four clock signals divided from the watch clock (φw) *
Asynchronous event counter: 16-bit timer
 Count-up timer able to count asynchronous external events
independently of the MCU's internal clocks
Timer C: 8-bit timer
 Count-up/down timer with selection of seven internal clock signals or
event input from external pin
 Auto-reloading
Timer F: 16-bit timer
 Can be used as two independent 8-bit timers
 Count-up timer with selection of four internal clock signals or event
input from external pin
 Provision for toggle output by means of compare-match function
Timer G: 8-bit timer
 Count-up timer with selection of four internal clock signals
 Incorporates input capture function (built-in noise canceler)
Watchdog timer
 Reset signal generated by overflow of 8-bit counter
SCI1: Synchronous serial interface
Choice of 8-bit or 16-bit transfer data
SCI3-1: 8-bit synchronous/asynchronous serial interface
Incorporates multiprocessor communication function
SCI3-2: 8-bit synchronous/asynchronous serial interface
Incorporates multiprocessor communication function
Can be used as a 14-bit D/A converter by connecting to an external low-
pass filter.
