Programmability
SPI Interface
The MC13783 IC contains two SPI interface ports which allow parallel access by both the call processor
and the applications processor to the MC13783 register set. Via these registers the MC13783 resources can
be controlled. The registers also provide status information about how the MC13783 IC is operating as
well as information on external signals. The SPI interface is comprised of the signals listed below.
