HIGH PERFORMANCE QUAD PCI-EXPRESS UART
MPIOSEL [15:0](default 0xFF)
The MPIOSEL register defines the MPIOs as either an input or output. A logic 1 (default) defines the pin for
input and a logic 0 for output.
MPIOOD [15:0] (default 0x00)
The MPIO outputs can behave as an open-drain output by the MPIOOD register. When the MPIOOD register is
a logic 0 (default), the MPIO is not an open-drain output. A logic 1 enables the MPIO as an open-drain output.
This register has no effect, when the MPIO is an input.
