Terminal Control (TCON) Register

This register contains 8 control bits. Four bits are for

Wiper 0, and four bits are for Wiper 1. Register 4-1

describes each bit of the TCON register.

The state of each resistor network terminal connection

is individually controlled. That is, each terminal

connection (A, B and W) can be individually connected/

disconnected from the resistor network. This allows the

system to minimize the currents through the digital

potentiometer.

The value that is written to this register will appear on

the

resistor

network

terminals

when

the

serial

command has completed.

When the WL1 bit is enabled, writes to the TCON

When the WL0 bit is enabled, writes to the TCON

On a POR/BOR this register is loaded with 1FFh

(9-bits),

for

all

terminals

connected.

The

Host

Controller needs to detect the POR/BOR event and

then update the volatile TCON register value.

Additionally, there is a bit which enables the operation

of General Call commands.
