DOUT Pin Output Data (Si3211/Si3212 only).
0 = DOUT pin driven low.
1 = DOUT pin driven high.
Si3210 = Reserved.
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.
