Mode Select (Bit 8)
The Mode Select bit selects between continuous PWM cycling
and one shot mode. The default is continuous repeat.
1: Enable One Shot mode. The mode runs the number of counter
cycles set in the PWM Cycle Count register and then stops.
0: Enable Continuous mode. Runs in continuous mode and
starts over after the PWM cycle count is reached.
PWM 3 Polarity Select (Bit 7)
The PWM 3 Polarity Select bit selects the polarity for PWM 3.
1: Sets the polarity to active HIGH or rising edge pulse
0: Sets the polarity to active LOW
PWM 2 Polarity Select (Bit 6)
The PWM 2 Polarity Select bit selects the polarity for PWM 2.
1: Sets the polarity to active HIGH or rising edge pulse
0: Sets the polarity to active LOW
PWM 1 Polarity Select (Bit 5)
The PWM 1 Polarity Select bit selects the polarity for PWM 1.
1: Sets the polarity to active HIGH or rising edge pulse
0: Sets the polarity to active LOW
PWM Maximum Count Register [0xC0E8] [R/W]
Table 127. PWM Maximum Count Register
Register Description
The PWM Maximum Count register designates the maximum
window for each pulse cycle. Each count tick is based on the
clock frequency set in the PWM Control register.
