Description
Output Enable A
Enables or disables output on PWM (D/A) channel A.
0: PWM (D/A) channel A output (at the PWX0 pin) is
1: PWM (D/A) channel A output (at the PWX0 pin) is
Output Select
Selects the phase of the PWM (D/A) output.
0: Direct PWM (D/A) output
1: Inverted PWM (D/A) output
Clock Select
Selects the PWM (D/A) resolution. If the system clock
( ) frequency is 10 MHz, resolutions of 100 ns and 200
ns, can be selected.
0: Operates at resolution (T) = system clock cycle time
1: Operates at resolution (T) = system clock cycle time
