4.2.1.2
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.
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.
