This register contains 8 control bits. Four bits are for
Wiper 0, and four bits are for Wiper 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.

Terminal Control (TCON) Register
Register 4-2
MCP414X/416X/424X/426X
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
register bits R1HW, R1A, R1W, and R1B are inhibited.
When the WL0 bit is enabled, writes to the TCON
register bits R0HW, R0A, R0W, and R0B are inhibited.
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.
