Note 1: Output is set for Port P32 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.

0 : Outputs "H" for the period set by Timer Y primary and
"L" for the period set by Timer Y secondary.
"L" is outputted when the timer is stopped.
