Note 1: In programmable waveform generation mode, port P32 is set for output regardless of the value of the direction
register.
Note 2: When this bit is cleared to "0", the timer reloads the content of the reload register before it stops. Read out the
count value before you stop the timer.
Note 3: When timer Z operation mode bit is set for "01", "10" or "11", port P31 is set for output regardless of the value of
the direction register.
