Description
The CHOP settings for the remote sensor.
00 = Auto chop. Change every MUX frame.
01 = Positive
10 = Negative
11 = Auto chop (same as 00)
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.

Programs the direction of the first 15 DIO pins. 1 indicates output. See DIO_PV and
DIO_PW for special option for DIO0 and DIO1 outputs. See DIO_EEX[1:0] for special
option for DIO2 and DIO3. Note that the direction of DIO pins above 14 is set by
DIOx[1]. See PORT_E to avoid power up spikes.
The value on the first 15 DIO pins. When written, changes data on pins configured
as outputs. Pins as input ignore writes. Note that the data for DIO pins above 14 is
set by DIOx[0].
When set, converts DIO3 and DIO2 to interface with external EEPROM. DIO2
becomes SDCK and DIO3 becomes bi-directional SDATA.
