27.2.1 PWM Enable Register (PWME)
Each PWM channel has an enable bit (PWMEn) to start its waveform output. While in run mode, if all
eight PWM output channels are disabled (PWME[7:0] = 0), the prescaler counter shuts off for power
savings. See
Section 27.3.2.1, “PWM Enable” for more information.

Field Description
7
PWME5
PWM Channel 7 Output Enable. If enabled, the PWM signal becomes available at PWMOUT7 when its
corresponding clock source begins its next cycle.
0 PWM output disabled
1 PWM output enabled
6
PWME6
PWM Channel 6 Output Enable. If enabled, the PWM signal becomes available at PWMOUT6 when its
corresponding clock source begins its next cycle. If PWMCTL[CON67] is set, then this bit has no effect and
PWMOUT6 is disabled.
0 PWM output disabled
1 PWM output enabled
5
PWME5
PWM Channel 5 Output Enable. If enabled, the PWM signal becomes available at PWMOUT5 when its
corresponding clock source begins its next cycle.
0 PWM output disabled
1 PWM output enabled
4
PWME4
PWM Channel 4 Output Enable. If enabled, the PWM signal becomes available at PWMOUT4 when its
corresponding clock source begins its next cycle. If PWMCTL[CON45] is set, then this bit has no effect and
PWMOUT4 is disabled.
0 PWM output disabled
1 PWM output enabled
3
PWME3
PWM Channel 3 Output Enable. If enabled, the PWM signal becomes available at PWMOUT3 when its
corresponding clock source begins its next cycle.
0 PWM output disabled
1 PWM output enabled
2
PWME2
PWM Channel 2 Output Enable. If enabled, the PWM signal becomes available at PWMOUT2 when its
corresponding clock source begins its next cycle. If PWMCTL[CON23] is set, then this bit has no effect and
PWMOUT2 is disabled.
0 PWM output disabled
1 PWM output enabled, if PWMCTL[CON23]=0
