Multi-function Timer (Max 3 units)
The Multi-function timer is composed of the following blocks.
Watch dog Timer (2 channels)
A watchdog timer can generate interrupts or a reset when a
time-out value is reached.
This series consists of two different watchdogs, a "Hardware"
watchdog and a "Software" watchdog.
"Hardware" watchdog timer is clocked by low speed internal
CR oscillator. Therefore, "Hardware" watchdog is active in any
power saving mode except STOP mode.
16-bit free-run timer × 3 ch./unit
Input capture × 4 ch./unit
Output compare × 6 ch./unit
A/D activation compare × 3 ch./unit
Waveform generator × 3 ch./unit
16-bit PPG timer × 3 ch./unit
The following function can be used to achieve the motor
control.

The Quadrature Position/Revolution Counter (QPRC) is used
to measure the position of the position encoder. Moreover, it is
possible to use up/down counter.

Watch Counter
The Watch counter is used for wake up from power saving
mode.
Interval timer: up to 64 s (Max) @ Sub Clock: 32.768 kHz
External OSC clock failure (clock stop) is detected, reset is
asserted.
External OSC frequency anomaly is detected, interrupt or
reset is asserted.
