6.5 QSPI Submodule
6.5.1 QSPI Pins
MC68332
MC68332TS/D
The QSPI submodule communicates with external devices through a synchronous serial bus. The QSPI
is fully compatible with the serial peripheral interface (SPI) systems found on other Motorola products.
A block diagram of the QSPI is shown below.
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.
