DEFAULT COMPARE REGISTER
FOR INTERRUPT-ON-CHANGE
The default comparison value is configured in the
DEFVAL register. If enabled (via GPINTEN and
INTCON) to compare against the DEFVAL register, an
opposite value on the associated pin will cause an
interrupt to occur.
REGISTER 1-4:
DEFVAL – DEFAULT VALUE REGISTER
R/W-0
DEF7
DEF6
DEF5
DEF4
DEF3
DEF2
DEF1
DEF0
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
DEF7:DEF0: Sets the compare value for pins configured for interrupt-on-change from defaults <7:0>.
Refer to INTCON.
If the associated pin level is the opposite from the register bit, an interrupt occurs.
Refer to INTCON and GPINTEN.
