NOTES:

3.
4.
When setting bits CMD1 to CMD0 to 10b or 11b, the MCU enters complementary PWM mode in spite of the setting of
the TRDPMR register.
Set bits CMD1 to CMD0 w hen both the TSTART0 and TSTART1 bits are set to 0 (count stops).
Set the ADCAP bit in the ADC0N0 register to 1 (starts by timer RD).
When bits CMD1 to CMD0 are set to 00b (timer mode, PWM mode, or PWM3 mode), the setting of the PWM3 bit is
enabled.
