NOTES :
1. TA0OUT pin is N-channel open drain output.
2. Effective w hen the TAiTGH and TAiTGL bits in the ONSF or TRGSR register are "00b" (TAiIN pin input).
3. The port direction bit for the TAiIN pin is set to "0" (= input mode).
4.
Set this bit to "1" (Pulse is output) to output PWM pulse.
5. Selected by PCLK0 bit in the PCLKR register.
