Section 10 8-Bit Timers
10.2.4
TCR0 and TCR1 are 8-bit readable/writable registers that select the clock source and the time at
which TCNT is cleared, and enable interrupts.
TCR0 and TCR1 are each initialized to H'00 by a reset and in hardware standby mode.
For details of this timing, see section 10.3, Operation.
Bit 7—Compare Match Interrupt Enable B (CMIEB): Selects whether CMFB interrupt
requests (CMIB) are enabled or disabled when the CMFB flag of TCSR is set to 1.

Bit 6—Compare Match Interrupt Enable A (CMIEA): Selects whether CMFA interrupt
requests (CMIA) are enabled or disabled when the CMFA flag of TCSR is set to 1.
