Bit 0 is read only. It reﬂects the interrupt type dictated by

the Parallel Port operation mode and conﬁgured by the

SuperI/O Parallel Port Conﬁguration register. This bit is

set to 1 (level interrupt) in Extended Mode and cleared

(edge interrupt) in all other modes.

Bit 1 is a read/write bit.

Bits 7-2 are read only.
