TCORB is an 8-bit readable/writable register.
TMR0.TCORB and TMR1.TCORB (TMR2.TCORB and TMR3.TCORB) comprise a single 16-bit register so they can
be accessed together by a word transfer instruction.
The value in TCORB is continually compared with the value in TCNT. When a match is detected, the corresponding
compare match B signal is set to high. Note however that comparison is not performed during writing to TCORB. The
timer output from the TMOn pin can be freely controlled by this compare match B signal and the settings of the
TCSR.OSB[1:0] bits.
