bit 8

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 8

D8: Reserved. Forced to ‘1’

bit 7

R3HW: Resistor 3 Hardware Configuration Control bit

This bit forces Resistor 3 into the “shutdown” configuration of the Hardware pin

1 = Resistor 3 is NOT forced to the hardware pin “shutdown” configuration

0 = Resistor 3 is forced to the hardware pin “shutdown” configuration

bit 6

R3A: Resistor 3 Terminal A (P3A pin) Connect Control bit

This bit connects/disconnects the Resistor 3 Terminal A to the Resistor 3 Network

1 = P3A pin is connected to the Resistor 3 Network

0 = P3A pin is disconnected from the Resistor 3 Network

bit 5

R3W: Resistor 3 Wiper (P3W pin) Connect Control bit

This bit connects/disconnects the Resistor 3 Wiper to the Resistor 3 Network

1 = P3W pin is connected to the Resistor 3 Network

0 = P3W pin is disconnected from the Resistor 3 Network

bit 4

R3B: Resistor 3 Terminal B (P3B pin) Connect Control bit

This bit connects/disconnects the Resistor 3 Terminal B to the Resistor 3 Network

1 = P3B pin is connected to the Resistor 3 Network

0 = P3B pin is disconnected from the Resistor 3 Network

bit 3

R2HW: Resistor 2 Hardware Configuration Control bit

This bit forces Resistor 2 into the “shutdown” configuration of the Hardware pin

1 = Resistor 2 is NOT forced to the hardware pin “shutdown” configuration

0 = Resistor 2 is forced to the hardware pin “shutdown” configuration

bit 2

R2A: Resistor 2 Terminal A (P0A pin) Connect Control bit

This bit connects/disconnects the Resistor 2 Terminal A to the Resistor 2 Network

1 = P2A pin is connected to the Resistor 2 Network

0 = P2A pin is disconnected from the Resistor 2 Network

bit 1

R2W: Resistor 2 Wiper (P0W pin) Connect Control bit

This bit connects/disconnects the Resistor 2 Wiper to the Resistor 2 Network

1 = P2W pin is connected to the Resistor 2 Network

0 = P2W pin is disconnected from the Resistor 2 Network

bit 0

R2B: Resistor 2 Terminal B (P2B pin) Connect Control bit

This bit connects/disconnects the Resistor 2 Terminal B to the Resistor 2 Network

1 = P2B pin is connected to the Resistor 2 Network

0 = P2B pin is disconnected from the Resistor 2 Network

Note 1:

These bits do not affect the wiper register values.
