Figure 60. PWM mode - (x8) programmable frequency
1. m = 0: n = 0, 1, or 2
PWM mode - fixed frequency, 16-bit
The operation of the 16-bit PWM is the same as the 8-bit PWM with fixed frequency. In this
mode, one or all the TCM can be configured to have a fixed frequency PWM output on the
port pins. The PWM frequency is depending on the clock input frequency to the 16-bit
Counter. The duty cycle of each TCM module can be specified in the CAPCOMHn and
CAPCOMLn registers. When the 16-bit PCA_Counter is equal or greater than the values in
registers CAPCOMHn and CAPCOMLn, the PWM output is switched to a high state. When
the PCA_Counter overflows, CEXn is asserted low.
