Enables IADC0-IADC1 differential configuration.
Enables IADC2-IADC3 differential configuration.
Enables IADC4-IADC5 differential configuration.
Enables IADC6-IADC7 differential configuration.
Connects PB and dedicated I/O pins DIO2 through DIO11 to internal resources. If more
than one input is connected to the same resource, the MULTIPLE column below specifies
how they are combined.

0 NONE –
1 Reserved OR
2 T0 (Timer0 clock or gate) OR
3 T1 (Timer1 clock or gate) OR
4 IO interrupt (int0) OR
5 IO interrupt (int1) OR
Programs the direction of the first 16 DIO pins. 1 indicates output. Ignored if the pin is
not configured as I/O. See DIO_PV and DIO_PW for special option for DIO0 and DIO1
outputs. See DIO_EEX[1:0] for special option for SEGDIO2 and SEGDIO3. Note that
the direction of DIO pins above 15 is set by SEGDIOx[1] . See PORT_E to avoid power-
up spikes.
The value on the first 16 DIO pins. Pins configured as LCD read zero. When written,
changes data on pins configured as outputs. Pins configured as LCD or input ignore
writes. Note that the data for DIO pins above 15 is set by SEGDIOx[0] .
