Timer Interface A (TIMA)
16.7.5 TIMA Channel Registers
These read/write registers contain the captured TIMA counter value of the input capture function or the
output compare value of the output compare function. The state of the TIMA channel registers after reset
is unknown.
In input capture mode (MSxB:MSxA = 0:0), reading the high byte of the TIMA channel x registers
(TACHxH) inhibits input captures until the low byte (TACHxL) is read.
In output compare mode (MSxB:MSxA ≠ 0:0), writing to the high byte of the TIMA channel x registers
(TACHxH) inhibits output compares until the low byte (TACHxL) is written.
