· PWM Programming Example

The following sample program shows how the PWM0 output is setup and controlled.

mov a,64h

; setup PWM value of decimal 100

mov pwm0,a

set ctrl0.5

; select the 7+1 PWM mode

set ctrl0.3

; select pin PA4 to have a PWM function

clr pac.4

; setup pin PA4 as an output

set pa.4

; enable the PWM output

clr pa.4

; disable the PWM output _ pin

; PA4 forced low
