6.2.6.2 PWM components
6.2.6.3 PWM counter
6.2.6.4 PWM frequency (F
the counter and decides on PWM frequency compared to the PWMD. The mode is used in low
frequency application simply.
PWM counter clock value is determined by the setting of PWMCON[6:4] (Prescaled Cock Selection for
PWM).
Table 6-9 PWM clock rate by PWMCON[6:4]
The 8-bit PWM circuits have the following components:
PWM counter operates in 8-bit counter mode. In this mode, the counter increments using all 8 bits in
The timing characteristics of PWM output are based on the prescaled F
Note: PWM clock (F
