Operations
This section describes the operations of the clock supervisor counter.

Clock Supervisor Counter
●
Clock Supervisor Counter Operation 1
The clock supervisor counter is first enabled by the software (CMCEN = 1), and then the clock
supervisor counter operates with the time-base timer interval selected from eight options by the
TBTSEL[2:0] bits. Between two rising edges of the time-base timer interval selected, the
internal counter is clocked by the external clock.
The count clock of this module can be selected from the main oscillation clock and the sub-
oscillation clock.

●
Clock Supervisor Counter Operation 2
The CMDR register is cleared when the CMCEN bit changes from "0" to "1".
