Notes:
1. Open collector and drain outputs need pull-up resistors on the motherboard.
2. These outputs can be pulled up to VCCIO or VCC_STDBY on the platform.
3. Pull-up resistance should limit current to 2 mA.
4. Actual V
OH
and V
OL
levels are determined by pull-up resistance and supply voltage values.
5. These values are based on 2.2 K pull-up to 3.3 V supply.
