Function Description
Timer 16-bit timer
pulse unit
(TPU)
• 16-bit timer × 12 channels (general pulse timer unit)
• Eight counter input clocks can be selected for each channel
• Maximum 16-pulse input/output (when external expanded mode is
set)
• Maximum 32-pulse input/output (when single-chip mode is set)
• Counter clear operation, simultaneous write to multiple timer
counters (TCNT), simultaneous clearing by compare match and
input capture, register simultaneous input/output possible by
counter synchronous operation, and maximum of 15-phase PWM
output by combination with synchronous operation
• Buffer operation, phase counting mode (two-phase encoder input),
and cascaded operation settable for channels
• Input capture function
• Output compare function (waveform output at compare match)
8-bit timer
(TMR)
• 8-bit timer × 2 channels (operation as a 16-bit timer is also possible)
• Selection of seven clock sources: Six internal clock signals or an
external clock input
• Pulse output with an arbitrary duty cycle or PWM output
Programma
ble pulse
generator
(PPG)
• 16-bit pulse output
• Pulse outputs are divided into four groups
Non-overlap mode is available
Inverted output can be specified
• Can operate together with the data transfer controller (DTC) and
DMA controller (DMAC)
Watchdog
timer
Watchdog
timer (WDT)
• 8-bit timer × 1 channel (eight counter input clocks can be selected)
• Switchable between watchdog timer mode and interval timer mode
Serial
interface
• Five channels (asynchronous or clocked synchronous serial
communication mode)
• Full-duplex communication capability
• Choice of any bit rate and choice of LSB-first or MSB-first
• IrDA data transmission/reception based on the IrDA standard
version 1.0
