Section 12 8-Bit Timers
TCSR0 and TCSR1 are 8-bit registers that display compare match and overflow statuses, and
control compare match output.
TCSR0 is initialized to H'00, and TCSR1 to H'10, by a reset and in hardware standby mode.
Bit 7—Compare Match Flag B (CMFB): Status flag indicating whether the values of TCNT and
TCORB match.
