Description
Timers
• 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
Two serial communication interface channels on chip
interface
• 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.
A/D converter
Successive approximations using a resistance ladder
• 8-channel analog input pins
• Conversion time: 31/ø or 62/ø per channel
LCD controller/driver
LCD controller/driver equipped with a maximum of 32 segment pins and
four common pins
• Choice of four duty cycles (static, 1/2, 1/3, or 1/4)
• Segment pins can be switched to general-purpose port function in 8-bit
units
LCD drive power
Step-up constant-voltage power supply allows LCD display
supply
