RESET:
ILSPI[2:0] determine the interrupt request levels of SPI interrupts. Program this field
to a value from $0 (interrupts disabled) through $7 (highest priority). If the interrupt-
request level programmed in this field matches the interrupt-request level pro-
grammed for one of the SCI interfaces and both request an interrupt simultaneously,
the SPI is given priority.
The MPAR determines which of the SPI pins, with the exception of the SCK pin, are
actually used by the SPI submodule, and which pins are available for general-purpose
I/O. The state of SCK is determined by the SPI enable bit in SPCR1. Clearing a bit in
MPAR assigns the corresponding pin to general-purpose I/O; setting a bit assigns the
pin to the SPI. Refer to
SPI pins designated by the MPAR as general-purpose I/O are controlled only by
MDDR and PORTMC. The SPI has no effect on these pins. The MPAR does not affect
the operation of the SCI submodule.
