5.3
Shutdown
Shutdown is used to minimize the device’s current
consumption. The MCP43XX has one method to
achieve this:
Terminal Control Register (TCON)
This is different from the MCP42XXX devices in that the
Hardware Shutdown pin (SHDN) has been replaced by
a RESET pin. The Hardware Shutdown pin function is
still available via software commands to the TCON
register.
5.3.1
TERMINAL CONTROL REGISTER
(TCON)
The Terminal Control (TCON) register is a volatile
register used to configure the connection of each
resistor network terminal pin (A, B and W) to the
Resistor Network. These registers are shown in
Register 4-1
and
Register
4-2.
The RxHW bit forces the selected resistor network into
the same state as the MCP42X1’s SHDN pin. Alternate
low-power configurations may be achieved with the
RxA, RxW and RxB bits.
When the RxHW bit is “0”:
• The P0A, P1A, P2A and P3A terminals are
disconnected
• The P0W, P1W, P2W and P3W terminals are
simultaneously connect to the P0B, P1B, P2B and
P3B terminals, respectively (see
Figure
Note:
When the RxHW bit forces the resistor
network into the hardware SHDN state,
the state of the TCON0 or TCON1
register’s RxA, RxW and RxB bits is
overridden (ignored). When the state of
the RxHW bit no longer forces the resistor
network into the hardware SHDN state,
the TCON0 or TCON1 register’s RxA,
RxW and RxB bits return to controlling the
terminal connection state. In other words,
the RxHW bit does not corrupt the state of
the RxA, RxW and RxB bits.

MCP433X/435X
The RxHW bit does NOT corrupt the values in the
Volatile Wiper Registers nor the TCON register. When
the Shutdown mode is exited (RxHW bit = 1):
• The device returns to the Wiper setting specified
by the Volatile Wiper value
• The TCON register bits return to controlling the
terminal connection state
