4.2.1.1
Status (STATUS) Register
This register contains 5 status bits. These bits show the
state of the Shutdown bit. The STATUS register can be
accessed via the READ commands. Register 4-1
describes each STATUS register bit.
The STATUS register is placed at Address 05h.
REGISTER 4-1:
STATUS REGISTER
R-1
R-0
R-x
D8:D5
RESV
SHDN
RESV
bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 8-5
D8:D5: Reserved. Forced to “1”
bit 4-2
RESV: Reserved
bit 1
SHDN: Hardware Shutdown pin Status bit (Refer to Section 5.3 “Shutdown” for further information)
This bit indicates if the Hardware shutdown pin (SHDN) is low. A hardware shutdown disconnects the
Terminal A and forces the wiper (Terminal W) to Terminal B (see Figure 5-2). While the device is in Hard-
ware Shutdown (the SHDN pin is low) the serial interface is operational so the STATUS register may be
read.
1
= MCP4XXX is in the Hardware Shutdown state
0
= MCP4XXX is NOT in the Hardware Shutdown state
bit 0
RESV: Reserved
