HIGH PERFORMANCE DUAL PCI EXPRESS UART
REV. 1.0.3
MPIOINT [15:0] (default 0x00)
The MPIOINT register enables the multipurpose input pin interrupt. If an MPIO pin is selected by MPIOSEL as
an input, then it can be selected to generate an interrupt. MPIOINT bit[0] enables input pin MPIO0 for interrupt,
and bit [7] enables input pin 7. No interrupt is enable if the pin is selected to be an output. The interrupt is edge
sensing and determined by MPIOINV and MPIOLVL registers. The MPIO interrupt clears after a read to
register MPIOLVL. The combination of MPIOLVL and MPIOINV determines the interrupt being active LOW or
active HIGH. Logic 0 (default) disables the pin’s interrupt and logic 1 enables it.

MPIOLVL [15:0] (default 0x00)
The MPIOLVL register controls the output pins and provides the input level status for the input pins. The status
of the input pin(s) is read on this register and output pins are controlled on this register. A logic 0 (default) sets
the output to LOW and a logic 1 sets the output pin to HIGH. The MPIO interrupt will clear upon reading this
register.

MPIO3T [15:0] (default 0x00)
The MPIO outputs can be tri-stated by the MPIO3T register. A logic 0 (default) sets the output to active level
per register MPIOBIT settling, a logic 1 sets the output pin to tri-state.

MPIOINV [15:0] (default 0x00)
The MPIO inputs can be inverted by the MPIOINV register. A logic 0 (default) does not invert the input pin logic.
A logic 1 inverts the input logic level.
