Section 12 8-Bit Timers
12.2.2
TCORA is an 8-bit readable/writable register.
TCORA0 and TCORA1 comprise a single 16-bit register, so they can be accessed together by
word access.
TCORA is continually compared with the value in TCNT. When a match is detected, the
corresponding compare-match flag A (CMFA) in TCSR is set. Note, however, that comparison is
disabled during the T2 state of a TCORA write cycle.
The timer output can be freely controlled by these compare-match signals and the settings of
output select bits OS1 and OS0 in TCSR.
TCORA is initialized to H'FF by a reset and in hardware standby mode.
