Terminal Control (TCON) Register

This register contains 8 control bits. Four bits are for

Wiper 0, and four bits are for Wiper 1. Register 4-2

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

HostController needs to detect the POR/BOR event

and then update the Volatile TCON register value.
