5.4.1 QSPI Pins
MC68331TS/D
Seven pins are associated with the QSPI. When not needed for a QSPI application, they can be con-
figured as general-purpose I/O pins. The PCS0/SS pin can function as a peripheral chip select output,
slave select input, or general-purpose I/O. Refer to the following table for QSPI input and output pins
and their functions.
