INTERRUPT CAPTURE REGISTER
The INTCAP register captures the GPIO port value at
the time the interrupt occurred. The register is ‘read
only’ and is updated only when an interrupt occurs. The
register will remain unchanged until the interrupt is
cleared via a read of INTCAP or GPIO.
REGISTER 1-9:
INTCAP – INTERRUPT CAPTURED VALUE FOR PORT REGISTER (ADDR 0x08)
R-x
ICP7
ICP6
ICP5
ICP4
ICP3
ICP2
ICP1
ICP0
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 7-0
ICP7:ICP0: These bits reflect the logic level on the port pins at the time of interrupt due to pin change
<7:0>
1 = Logic-high.
0 = Logic-low.
