General Purpose I/O
Each of the SPI pins may be programmed via the SPI Pin Control Registers
(SPIPC1, SPIPC2, SPIPC3, SPIPC4, SPIPC5, SPIPC6) to be a general-
purpose I/O pin.
When the MibSPI module is not used, the MibSPI pins may be programmed
to be either general input or general output pins. The direction is controlled in
the SPIPC1 register. Note that each pin can be programmed to be either a
SPI pin or a GPIO pin through register SPIPC6.
If the MibSPI function is used, application software must ensure that each pin
is configured as a MibSPI pin and not a GPIO pin, or else unexpected
behavior may result.
