Timer Interface Module B (TIMB)
TIMB channel
registers (TBCH0H/
LÐTBCH3H/L)
These read/write registers contain the captured TIMB counter value of
the input capture function or the output compare value of the output
compare function. The state of the TIMB channel registers after reset is
unknown.
In input capture mode (MSxB:MSxA = 0:0), reading the high byte of the
TIMB channel x registers (TBCHxH) inhibits input captures until the low
byte (TBCHxL) is read.
In output compare mode (MSxB:MSxA ≠ 0:0), writing to the high byte of
the TIMB channel x registers (TBCHxH) inhibits output compares until
the low byte (TBCHxL) is written.
