USER’S MANUAL
FOC[5:1] correspond to OC[5:1].
This field selects one of seven prescaler taps or PCLK to be PWMCNT input. Refer to
Table D-52.
Table D–53 shows a range of PWM output frequencies using a 16.78 MHz system
clock.
0 = Has no effect.
1 = Causes pin action programmed for corresponding OC pin, but the OC flag is
0 = PWM pin A/B is used for PWM functions; normal operation.
1 = PWM pin A/B is used for discrete output. The value of the F1A/B bit will be driv-
0 = Normal PWM operation on PWMA.
1 = Clock selected by PPR[2:0] is driven out PWMA pin.
0 = PWMA period is 256 PWMCNT increments long.
1 = PWMA period is 32768 PWMCNT increments long.
0 = PWMB period is 256 PWMCNT increments long.
1 = PWMB period is 32768 PWMCNT increments long.
not set. FOC[5:1] correspond to OC[5:1].
en out on the PWMA/B pin. This is true for PWMA regardless of the state of the
PPROUT bit.
