These read/write registers (TCH0H/L and TCH1H/L) contain the
captured TIM counter value of the input capture function or the output
compare value of the output compare function. The state of the TIM
channel registers after reset is unknown.
In input capture mode (MSxB:MSxA = 0:0), reading the high byte of the
TIM channel x registers (TCHxH) inhibits input captures until the low
byte (TCHxL) is read.
In output compare mode (MSxB:MSxA 0:0), writing to the high byte of
the TIM channel x registers (TCHxH) inhibits output compares until the
low byte (TCHxL) is written.
