Description
• Timer B: 8-bit timer
 Count-up timer with selection of seven internal clock signals or
event input from external pin
 Auto-reloading
• Timer C: 8-bit timer
 Count-up/count-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
 Compare-match function with toggle output
• Timer G: 8-bit timer
 Count-up timer with selection of four internal clock signals
 Input capture function with built-in noise canceller circuit
Three channels on chip
• SCI1: synchronous serial interface
Choice of 8-bit or 16-bit data transfer
• SCI2: 8-bit synchronous serial interface
Automatic transfer of 32-byte data segments
• SCI3: 8-bit synchronous or asynchronous serial interface
Built-in function for multiprocessor communication
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.
• Successive approximations using a resistance ladder resolution:
8 bits
• 12-channel analog input port
• Conversion time: 31/φ or 62/φ per channel
Up to 40 segment pins and 4 common pins
• Choice of four duty cycles (static, 1/2, 1/3, 1/4)
• Segments can be expanded externally
• Segment pins can be switched to general-purpose ports in groups of
four
