TCORB is an 8-bit readable/writable register. TCORB0 and TCORB1 comprise a single 16-bit
register, so they can be accessed together by word access.
TCORB is continually compared with the value in TCNT. When a match is detected, the
corresponding compare-match flag B (CMFB) in TCSR is set. Note, however, that comparison is
disabled during the T2 state of a TCORB write cycle.
The timer output can be freely controlled by these compare-match signals and the settings of
output select bits OS3 and OS2 in TCSR.
TCORB is initialized to H'FF by a reset and in hardware standby mode.
