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.

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: Reflects the interrupt condition on the port. Will reflect the change only if interrupts are

enabled (GPINTEN) <7:0>.

= Pin caused interrupt.

= Interrupt not pending.
