Got to SUB-20 page

Fast PWM outputs are available on SPI header pins 4,6,8 (see SPI Header). Outputs are referenced as FPWM_0, FPWM_1 and FPWM_2. All three outputs share the same PWM generation module in SUB-20 and have the same PWM frequency but separate duty cycle configuration.

 

fast-PWM

 

Fast PWM frequency range is 8Mhz .. 0.238Hz. Duty cycle precision is 2..16 bits depending on the PWM frequency.
