PWM register (PWM) [Address : 2D16]
Function
“H” level output period of PWM is set.
The values set in this register is written both the PWM register
pre-latch and the PWM register latch at the same time.
When data is written during outputting PWM, the pulses
corresponding to the changed contents are output starting with
the next cycle.
When this register is read out, the content of the PWM register
latch is read out.
