DCI can support up to 16 time slots in a data frame for
a maximum frame size of 256 bits. There are control

8.8
The Serial Peripheral Interface (SPI) module is a
synchronous serial interface for communicating with
other peripheral or microcontroller devices such as
serial EEPROMs, shift registers, display drivers, A/D
Converters, etc. It is compatible with Motorola
SIOP interfaces.
This SPI module includes all SPI modes. A Frame
Synchronization mode is also included for support of
voice band codecs.
Four pins make up the serial interface: SDI, Serial Data
Input; SDO, Serial Data Output; SCK, Shift Clock Input
or Output; SS, Active-Low Slave Select, which also
serves as the FSYNC (Frame Synchronization Pulse).
A device set up as an SPI master provides the serial
communication clock signal on its SCK pin.

bits for each time slot in the data frame that determine
whether the DCI will transmit/receive during the time
slot. The DCI module supports DMA data transfers.
A series of 8 or 16 clock pulses (depending on mode)
shift out the 8 or 16 bits (depending on whether a byte
or word is being transferred) and simultaneously shift in
8 or 16 bits of data from the SDI pin. An interrupt is
generated when the transfer is complete.
Slave select synchronization allows selective enabling
of SPI slave devices, which is particularly useful when
a single master is connected to multiple slaves.
The SPI1 and SPI2 modules support DMA data
transfers.
