1 : Starts counting
RW
Note 1: When selecting programmable waveform generation mode, output is set for Port P31 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.

Timer Z output level
latch
0 : Outputs "H" for the period set by Timer Z primary and
"L" for the period set by Timer Z secondary.
"L" is outputted when the timer is stopped.
1 : Outputs "L" for the period set by Timer Z primary and
RW
"H" for the period set by Timer Z secondary.
"H" is outputted when the timer is stopped.
