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
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)
8-bit timer × 1 channel (eight counter input clocks can be
selected)
Switchable between watchdog timer mode and interval timer
mode
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
Four channels
Continuous transmission/reception
Start and stop conditions generated automatically in master
mode
Selection of acknowledge output levels when receiving
Automatic loading of acknowledge bit when transmitting
Bit synchronization/wait function
One channel
Master mode or slave mode can be selected
Standard mode or bidirectional mode can be selected
Full-duplex communication capability
Consecutive serial communication capability
