MPIOINT [7:0] (default 0x00)
Enable multipurpose input pin interrupt. If the pin is
selected by MPIOSEL as input then bit-0 enables in-
put pin 0 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 in-
terrupt clears after a read to register MPIOLVL. The
combination of MPIOLVL and MPIOINV determines
the interrupt being active low or active high, it’s level
trigger. Logic 0 (default) disables the pin’s interrupt
and logic 1 enables it.
MPIOLVL [7:0] (default 0x00)
Output pin level control and input level status. 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 [7:0] (default 0x00)
Output pin tri-state control. A logic 0 (default) sets
the output to active level per register MPIOBIT set-
tling, a logic 1 sets the output pin to tri-state.
