12.2.4
TCR is an 8-bit readable/writable register that selects the clock source and the time at which
TCNT is cleared, and enables interrupts.
TCR is initialized to H'00 by a reset and in hardware standby mode.
For details of the timing, see section 12.3, Operation.
Bit 7—Compare-Match Interrupt Enable B (CMIEB): Selects whether the CMFB interrupt
request (CMIB) is enabled or disabled when the CMFB flag in TCSR is set to 1.
Note that a CMIB interrupt is not requested by TMRX, regardless of the CMIEB value.
Bit 6—Compare-Match Interrupt Enable A (CMIEA): Selects whether the CMFA interrupt
request (CMIA) is enabled or disabled when the CMFA flag in TCSR is set to 1.
Note that a CMIA interrupt is not requested by TMRX, regardless of the CMIEA value.
