Revision 1.07
PWM Polarity Register (PWMPOL)
This register controls the polarity of PWM0 to PWM7. The register is cleared (0016) on reset.
Location: 00 FD0416
Type: R/W
PWM Control Register (PWMCNT)
This register controls PWM operation. The register is cleared (0016) on reset.
Location: 00 FD0616
Type: R/W

Bit
Description
7-0
Inverse PWM Outputs. Each bit controls the corresponding polarity of PWM0 to PWM7; e.g., INVP0 controls
PWM0.
0: The number in DCRi indicates for how many clocks (of down-counter decrements) PWMi signal is high.
1: The number in DCRi indicates for how many clocks (of down-counter decrements) PWMi signal is low.

Bit
Description
0
Power Mode. This bit controls the operating mode of the PWM, as follows:
0: Low Power mode. PWM input clock is disabled (stopped). Its registers are accessible and maintained. PWMi
signal is 0 when INVPi bit is 0. PWMi signal is 1 when INVPi bit is 1.
1: Normal Power mode. PWM module is enabled. Its registers are accessible and its clock is functional.
