R/W
Output Enable B
Enables or disables output on PWM (D/A) channel B.
0: PWM (D/A) channel B output (at the PWX1 pin) is
disabled
1: PWM (D/A) channel B output (at the PWX1 pin) is
enabled

R/W
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
disabled

Clock Select
Selects the PWM (D/A) resolution. If the system clock
(
φ
) frequency is 10 MHz, resolutions of 100 ns, 200 ns,
6,400 ns, and 12,800 ns can be selected.
0: Operates at resolution (T) = system clock cycle time
