BANK
MIRROR
SEQOP
DISSLW
HAEN
ODR
INTPOL
—
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 7
BANK: Controls how the registers are addressed
1 = The registers associated with each port are separated into different banks
0 = The registers are in the same bank (addresses are sequential)
bit 6
MIRROR: INT Pins Mirror bit
1 = The INT pins are internally connected
0 = The INT pins are not connected. INTA is associated with PortA and INTB is associated with PortB
bit 5
SEQOP: Sequential Operation mode bit.
1 = Sequential operation disabled, address pointer does not increment.
0 = Sequential operation enabled, address pointer increments.
bit 4
DISSLW: Slew Rate control bit for SDA output.
1 = Slew rate disabled.
0 = Slew rate enabled.
bit 3
HAEN: Hardware Address Enable bit (MCP23S17 only).
Address pins are always enabled on MCP23017.
1 = Enables the MCP23S17 address pins.
0 = Disables the MCP23S17 address pins.
bit 2
ODR: This bit configures the INT pin as an open-drain output.
1 = Open-drain output (overrides the INTPOL bit).
0 = Active driver output (INTPOL bit sets the polarity).
bit 1
INTPOL: This bit sets the polarity of the INT output pin.
1 = Active-high.
0 = Active-low.
bit 0
Unimplemented: Read as ‘0’.
