PWI.0 as the input clock source. For channels 1 and 3,
this selection assigns PWI.1 as the input clock source.
PWnEN – PWM n Frequency Generator
Enable.
Enables the frequency generator for PWM n. When
PWnEN = 1, the frequency generator operates from the
11.5.2 PW01CON / PW23CON – PWM 0, 1 / PWM 2, 3 Control Register
PW01CON; SFR ADDR.=0DDH
PW23CON; SFR ADDR.=0EDH
Read/Write Access: Unrestricted.
Initialization: 00H on any type of reset
PWnF – PWM n Flag.
Indicates that the PWM n timer has rolled over to a zero
after a total of 256 counts. This bit must be cleared by
software to remove the flagged condition.
PWnDC – PWM n D. C. Override.
Setting this bit to a 1 forces the PWMn output to a 1
regardless of the PWM match value.
PWnOE – PWM n Output Enable.
When set to a 1, PWnOE enables the PWM channel’s
output on the associated port pin. The port pin’s normal
psuedo–bi–directional function is switched over to a full

clock selected by PWnS2–0. When PWnEN = 0, no
clock is generated.
complementary push–pull output drive. When cleared
to 0, the PWM function is disconnected, and the normal
port pin function is restored.
PWnT/C – PWM n Timer / Compare Value
Select.
PWnT/C controls whether the read/write access of the
PWM channel’s value register results in access of the
timer or the compare values. When PWnT/C = 1, the
Timer values are accessed via the PWM n SFR. When
PWnT/C = 0, the Compare values are accessed via the
PWM n SFR.
