Timer Control/Status Register V (TCSRV)
Note:
TCSRV is an 8-bit register that sets compare match flags and the timer overflow flag, and controls
compare match output.
TCSRV is initialized to H'10 upon reset and in standby mode, watch mode, subsleep mode, and
subactive mode.
Bit 7 Compare Match Flag B (CMFB): Bit 7 is a status flag indicating that TCNTV has
matched TCORB. This flag is set by hardware and cleared by software. It cannot be set by
software.

Bit 6 Compare Match Flag A (CMFA): Bit 6 is a status flag indicating that TCNTV has
matched TCORA. This flag is set by hardware and cleared by software. It cannot be set by
software.
