Open-Drain Option Register
This PWM Open-Drain option Register contains 8 bits which are programmed to change
the output drive of individual PWM channel from channel 0 to channel 7 to be open-drain
type. This register is located at $0012
Figure 8-3: PWM Open-Drain Option Register
When any bit in this register is one, the corresponding PWM channel output becomes +5V
open-drain type. When the bit is zero, the corresponding PWM channel has push-pull
output. All eight bits are clear upon reset.
