Section 17 Subsystem Timer (Subtimer)
17.5
17.5.1
When the on-chip oscillator for the subtimer is used to supply clocks to the watchdog timer, the
setting is necessary not only for the subtimer but also for the watchdog timer. For details, refer to
section 13, Watchdog Timer.
17.5.2
ROPCR must be written to in active mode with the PCEF bit in SBTCTL set to 1. Otherwise, the
subtimer may operate incorrectly.
