Prescaler mode
register 01 (PRM01)
Cautions 1. The valid edge of TI010 and timer output (TO00) cannot be used for the P01 pin at the same
TM0n is a 16-bit read-only register that counts count pulses.
The counter is incremented in synchronization with the rising edge of the count clock.
If the count value is read during operation, then input of the count clock is temporarily stopped, and the count
value at that point is read.

A value that has been once captured remains stored in CR00n unless the device is reset. If
the mode has been changed to the comparison mode, be sure to set a comparison value.
