16.2 Overview
The SPI can communicate with other external SPI devices. It provides flexibility to communicate with different SPI
compatible circuits from several manufacturers (Serial EEPROMs, display drivers, A/D converters, audio device).
Four dedicated input or output pads are attached to the SPI block: MISO, MOSI, SCK, NSS.
Six registers are used to run the SPI block. RegSpiControl, RegSpiStatus, RegSpiDataOut, RegSpiDataIn,
RegSpiPullup, RegSpiDir are used to configure the communication settings, read the flags, write and read the
exchanged data, and for the pad settings.
The SPI device can also be used as a 4 bit general purpose input/output port.
16.3 Register map
When the peripheral is used as a general-purpose parallel I/O port, the SPI pads are mapped in the registers as
follows (RegSpiDataOut, RegSpiDatain, RegSpiPullup and RegSpiDir):
