12-bit PPG timer
Output frequency : Pulse width and cycle selectable
External interrupt 1
(wake-up function)
3 independent channels (Interrupt vector, request flag, request output enabled)
Rising/falling/both edge selectable
Used for wake-up from stop/sleep mode. (Edge detection is also permitted in the stop
mode.)
External interrupt 2
(wake-up function)
8 channels (low-level interrupt only)
Used for wake-up from stop/sleep mode. (Edge detection is also permitted in the stop
mode.)
