Fig. 31 Structure of PWM control register
Fig. 32 PWM output timing when PWM register or PWM prescaler is changed
sNote
The PWM starts after the PWM function enable bit is set to enable and “L” level is output from the PWM pin.
The length of this “L” level output is as follows:
sec
(Count source selection bit = 0, where n is the value set in the prescaler)
sec
(Count source selection bit = 1, where n is the value set in the prescaler)
n+1
2 f(XIN)
n+1
f(XIN)
PWM control register
(PWMCON : address 001D16)
PWM function enable bit
Count source selection bit
Not used (return “0” when read)
b7
b0
0: PWM disabled
1: PWM enabled
0: f(XIN) (f(XCIN) at low-speed mode)
1: f(XIN)/2 (f(XCIN)/2 at low-speed mode)

(Changes “H” term from “A” to “B”.)
(Changes PWM period from “T” to “T2”.)
When the contents of the PWM register or PWM prescaler have changed, the PWM
output will change from the next period after the change.
