17.2.4
The module supports a very basic framed SPI protocol
while operating in either Master or Slave modes. The
following features are provided in the SPI module to
support Framed SPI modes:
• The control bit, FRMEN (SPIxCON<31>), enables
• The control bit, FRMSYNC (SPIxCON<30>),
• The FRMPOL (SPIxCON<29>) determines the

used as a frame synchronization pulse input or
output pin. The state of the SSEN (SPIxCON<7>)
is ignored.
determines whether the SSx pin is an input or an
output (i.e., whether the module receives or
generates the frame synchronization pulse).
frame synchronization pulse polarity for a single
SPI clock cycle.
Note 1: In Framed SPI modes, the SSx pin is used to transmit/receive the frame synchronization pulse.
FRAMED SPI MODES
2: Framed SPI modes require the use of all four pins, i.e., using the SSx pin is not optional.
3: The SPIxTXB and SPIxRXB registers are memory mapped to the SPIxBUF register.

The following framed SPI modes are supported by the
SPI module:
• Frame Master mode: The SPI module generates
• Frame Slave mode: The SPI module uses a frame
The Framed SPI modes are supported in conjunction
with the Master and Slave modes. Thus, the following
framed SPI configurations are available:
• SPI Master mode and Frame Master mode
• SPI Master mode and Frame Slave mode
• SPI Slave mode and Frame Master mode
• SPI Slave mode and Frame Slave mode
These four modes determine whether or not the SPI
module generates the serial clock and the frame
synchronization pulse.
