INTERRUPT-ON-CHANGE
CONTROL REGISTER
The GPINTEN register controls the interrupt-on-
change feature for each pin.
If a bit is set, the corresponding pin is enabled for
interrupt-on-change. The DEFVAL and INTCON
registers must also be configured if any pins are
enabled for interrupt-on-change.
REGISTER 1-3:
GPINTEN – INTERRUPT-ON-CHANGE PINS (ADDR 0x02)
R/W-0
GPINT7
GPINT6
GPINT5
GPINT4
GPINT3
GPINT2
GPINT1
GPINT0
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
GPINT7:GPINT0: General purpose I/O interrupt-on-change bits <7:0>
1 = Enable GPIO input pin for interrupt-on-change event.
0 = Disable GPIO input pin for interrupt-on-change event.
Refer to INTCON and GPINTEN.
