It is the responsibility of the system software to set the logic level on the
TIMER pin to the desired value before involving the PWM mode.
When the TIMER_MS field is set to 011 to start the PWM signal, the first
period is at the logic level specified by the PWMOP bit. The active pulse
whose width is specified by the WIDTH field overlays the following period.
In the present example, it is assumed that the TIMER pin is at a logic 0 at
the time that the TIMER_MS field is written. From a practical standpoint,
this effectively means that the first active pulse occurs one full PWM period
after writing the TIMER_MS field. If the TIMER pin is at a logic 1 at the
time that the TIMER_MS field is written, it appears as though the first pulse
is one full PWM period wide. Therefore, it is important to program the
TIMER pin such that it is in a known state before writing to the TIMER_MS
field.
