11.6.4 16-Bit PPG Mode
The Timer 3/4/5/6 has a PPG (Programmable Pulse Generation) function. In PPG mode, T3O/PWM3O, T4O/PWM4O,
T5O/PWM5O and T6O/PWM6O pin outputs up to 16-bit resolution PWM output. This pin should be configured as a
PWM output by setting P1FSR[1:0] to ‘01’, P1FSR[2] to ‘1’, P1FSR[3] to ‘1’ and P1FSR[4] to ‘1’. The period of the
PWM output is determined by the TnADRH/TnADRL. And the duty of the PWM output is determined by the
TnBDRH/TnBDRL.

NOTE)
1. The TnEN is automatically cleared to logic “0” after one pulse is generated at a PPG one-shot
mode.
2. Do not set to “110b” in the TnCK[2:0], when fx is over 10MHz.
