Timer Control Register V0 (TCRV0)
TCRV0 is an 8-bit read/write register that selects the TCNTV input clock, controls the clearing of
TCNTV, and enables interrupts.
TCRV0 is initialized to H'00 upon reset and in standby mode, watch mode, subsleep mode, and
subactive mode.
Bit 7 Compare Match Interrupt Enable B (CMIEB): Bit 7 enables or disables the interrupt
request (CMIB) generated from CMFB when CMFB is set to 1 in TCSRV.

Bit 6 Compare Match Interrupt Enable A (CMIEA): Bit 6 enables or disables the interrupt
request (CMIA) generated from CMFA when CMFA is set to 1 in TCSRV.
Bit 6: CMIEA

Bit 5 Timer Overflow Interrupt Enable (OVIE): Bit 5 enables or disables the interrupt
request (OVI) generated from OVF when OVF is set to 1 in TCSRV.
Bit 5: OVIE

Bits 4 and 3 Counter Clear 1 and 0 (CCLR1, CCLR0): Bits 4 and 3 specify whether or not to
clear TCNTV, and select compare match A or B or an external reset input.
When clearing is specified, if TRGE is set to 1 in TCRV1, then when TCNTV is cleared it is also
halted. Counting resumes when a trigger edge is input at the TRGV pin.
