Caution:
When the Timer Output alternate function TxOUT on a GPIO port pin is
enabled, TxOUT will change to whatever state the TPOL bit is in. The tim-
er does not need to be enabled for that to happen. Also, the Port data direc-
tion sub register is not needed to be set to output on TxOUT. Changing the
TPOL bit with the timer enabled and running does not immediately change
the TxOUT.
PRES—Prescale value.
The timer input clock is divided by 2^PRES, where PRES can be set from 0 to 7. The
prescaler is reset each time the Timer is disabled. This insures proper clock division
each time the Timer is restarted.
