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 MPIO3T settling, a
logic 1 sets the output pin to tri-state.
MPIOINV [7:0] (default 0x00)
Input inversion control. A logic 0 (default) does not invert the input pin logic. A logic 1 inverts the input logic
level.
MPIOSEL [7:0] (default 0xFF)
Multipurpose input/output pin select. This register defines the functions of the pins. A logic 1 (default) defines
the pin for input and a logic 0 for output.
