5.4
Shutdown
Shutdown is used to minimize the device’s current
consumption. The MCP44XX has one method to
achieve this. This is:
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Hardware Shutdown Pin (SHDN) has been replaced by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.
5.4.1
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 4-2 and Register 4-3.
The RxHW bits 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 5-2)
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
FIGURE 5-2:
Resistor Network Shutdown
State (RxHW = ‘0’).
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.
