Cautions 1. Clearing by match of the TM1n count value and CM1n0 set value
is valid only during TM1n up count operation (TM1n is not
cleared during TM1n down count operation).
2. When the CMD bit of the TUMn register = 0 (general-purpose
timer mode), the CLR1 and CLR0 bit settings are invalid.
3. When the MSEL bit of the TUMn register = 1 (UDC mode B), the
CLR1 and CLR0 bit settings are invalid.
4. When clearing by TCLR1n has been enabled with bits CLR1 and
CLR0, clearing is performed whether the value of the TM1CEn bit
is 1 or 0.
