Item Description
Timers Six on-chip timers
• 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
Serial
communication
interface
Three serial communication interface channels on chip
• 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
14-bit PWM Pulse-division PWM output for reduced ripple
• Can be used as a 14-bit D/A converter by connecting to an external low-
pass filter.
