INTERRUPT CONTROL REGISTER
The INTCON register controls how the associated pin
value is compared for the interrupt-on-change feature.
If a bit is set, the corresponding I/O pin is compared
against the associated bit in the DEFVAL register. If a
bit value is clear, the corresponding I/O pin is compared
against the previous value.
REGISTER 1-5:
INTCON – INTERRUPT-ON-CHANGE CONTROL REGISTER (ADDR 0x04)
R/W-0
IOC7
IOC6
IOC5
IOC4
IOC3
IOC2
IOC1
IOC0
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
IOC7:IOC0: These bits control how the associated pin value is compared for interrupt-on-change
<7:0>
1 = Controls how the associated pin value is compared for interrupt-on-change.
0 = Pin value is compared against the previous pin value.
Refer to INTCON and GPINTEN.
