8.4.2 Clear Operation
(1) Clear operation after a match with the compare register
(2) Clear operation by the CE0 bit of the timer control register 0 (TMC0)
The timer register 0 (TM0) can be cleared automatically after a match with the compare register (CR01). When a clearance
source arises, TM0 is cleared to 0000H on the next count clock. Therefore, even if a clearance source arises, the value
at the point at which the clearance source arose is retained until the next count clock arrives.
The timer register 0 (TM0) is also cleared when the CE0 bit of TMC0 is cleared (0) by software. The clear operation is
performed immediately after clearance (0) of the CE0 bit.
