https://en.wikipedia.org/wiki/Open_collector
- Bit 3: 0 means the output should be maintained during sleep/low-power mode
1 means the output state can be lost during sleep/low-power mode
- Bit 4: 0 means no pull-up resistor should be enabled
1 means a pull-up resistor should be enabled
This setting only applies to hardware with a simple on/off
control for pull-up configuration. If the hardware has more
elaborate pull-up configuration, it should be represented
using a pin control binding.
- Bit 5: 0 means no pull-down resistor should be enabled
1 means a pull-down resistor should be enabled
This setting only applies to hardware with a simple on/off
control for pull-down configuration. If the hardware has more
elaborate pull-down configuration, it should be represented
using a pin control binding.
