Description
CHOPR[1:0]
2709[7:6]
00 00 R/W
The CHOP settings for the remote sensor.
00 = Auto chop. Change every MUX frame.
01 = Positive
10 = Negative
11 = Auto chop. Same as 00.
DIFFA_E
210C[4]
0
R/W Enables differential configuration for the IA current input (IAP-IAN).
DIFFB_E
210C[5]
0
R/W Enables differential configuration for the IB current input (IBP-IBN).

R/W
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.

R/W
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 the SEGDIO0 and SEGDIO1 outputs. See DIO_EEX 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.

SFR B0[3:0]
SFR A0[3:0] SFR 90[3:0]
SFR 80[3:0]
F
R/W
The value on the first 16 DIO pins. Pins configured as LCD reads 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].
DIO_EEX[1:0]
2456[7:6]
0
R/W
When set, converts pins SEGDIO3/SEGDIO2 to interface with external
EEPROM. SEGDIO2 becomes SDCK and SEGDIO3 becomes bi-directional
SDATA, but only if LCD_MAP[2] and LCD_MAP[3] are cleared.
DIO_EEX[1:0]
Function
00
Disable EEPROM interface
01
2-Wire EEPROM interface
10
3-Wire EEPROM interface
11
3-Wire EEPROM interface with separate DO (DIO3)
and DI (DIO8) pins.
