MV64360 Multi-Purpose Port Configuration

The MV64360 contains a 32-bit multi-purpose port (MPP). The MPP pins can be configured as general purpose I/O pins, as external interrupt inputs, or as a specific control/status pin for one of the MV64360 internal devices. After reset, all MPP pins default to GPP pins (general purpose inputs).

Software must then configure each of the pins for the desired function. The
