DIO2 Pin Input/Output Direction.
0 = DIO2 pin is an input.
1 = DIO2 pin is an output and driven to value of the PD2 bit.
Si3210 = Reserved.
DIO1 Pin Input/Output Direction.
0 = DIO1 pin is an input.
1 = DIO1 pin is an output and driven to value of the PD1 bit.
Si3210 = Reserved.
DIO2 Pin Data.
When DIO2 = 1:
0 = DIO2 pin driven low.
1 = DIO2 pin driven high.
Si3210 = Reserved.
When DIO2 = 0, PD2 value equals the logic input of DIO2 pin.

PD1
DIO1 Pin Data.
When DIO1 = 1:
0 = DIO1 pin driven low.
1 = DIO1 pin driven high.
Si3210 = Reserved.
When DIO1 = 0, PD1 value equals the logic input of DIO1 pin.
