5.14. 11-bit PWM generation
Three 11-bit hardware PWM generators (PWMG0, PWMG1 & PWMG2) are implemented in the PFS154.
PWMG0 is used as the example to describe its functions due to all of them are almost the same. Their
individual outputs are listed as below:
 PWMG0 – PA0, PB4, PB5
 PWMG1 – PA4, PB6, PB7
 PWMG2 – PA3, PB2, PB3, PA5 (Note: PA5 open drain output only, users need to enable the internal
pull-high resistor or add an external pull-high resistor when using, and ICE does not support PA5 PWM
function.)

PWM Waveform
A PWM output waveform (Fig. 16) has a time-base (TPeriod = Time of Period) and a time with output high level
(Duty Cycle). The frequency of the PWM output is the inverse of the period (fPWM = 1/TPeriod), the resolution of
the PWM is the clock count numbers for one period (N bits resolution, 2
N × T
clock = TPeriod).
