INTERRUPT FLAG REGISTER
The INTF register reflects the interrupt condition on the
port pins of any pin that is enabled for interrupts via the
GPINTEN register. A ‘set’ bit indicates that the
associated pin caused the interrupt.
This register is ‘read-only’. Writes to this register will be
ignored.
REGISTER 1-8:
INTF – INTERRUPT FLAG REGISTER (ADDR 0x07)
R-0
INT7
INT6
INT5
INT4
INT3
INT2
INT1
INT0
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
INT7:INT0: These bits reflect the interrupt condition on the port. Will reflect the change only if interrupts
are enabled (GPINTEN) <7:0>.
1 = Pin caused interrupt.
0 = Interrupt not pending.
