Notes: 1. PWM mode 2 cannot be set for channels 3, 4.

2. Phase counting mode cannot be set for channels 0, 3, 4.

3. Reset synchronous PWM mode, complementary PWM mode can only be set for

channel 3. When channel 3 is set to reset synchronous PWM mode or complementary
PWM mode, the channel 4 settings become ineffective and automatically conform to the
channel 3 settings. However, do not set channel 4 to reset synchronous PWM mode or
complementary PWM mode. Reset synchronous PWM mode and complementary PWM
mode cannot be set for channels 0, 1, 2.
