PWM1CNT(A3h) : PWMA CH1 Counter Register
-
CPS2, CPS1, CPS0 : PWMA counter frequency selection.
PWMOVF : PWMA counter overflow flag.
PWMEN : PWMA counter run control bit.
Software can write this register for the initialization of the counter.

[0,0,0] = FOSC / 1 ; Default
[0,0,1] = FOSC / 2
[0,1,0] = FOSC / 4
[0,1,1] = FOSC / 8
[1,0,0] = FOSC / 16
[1,0,1] = FOSC / 32
[1,1,0] = FOSC / 64
[1,1,1] = FOSC / 128
Set by hardware and cleared by software.
PWMOVF flags an interrupt.
[0] = Stop the PWMA counter.
[1] = Run the PWMA counter.

Each Module has a internal buffer register for the duty data register.
The buffer register is updated with the new data whenever the
When user write, the data register is written.
When user read, the contents of buffer register is read out.
