15.0
The Serial Peripheral Interface (SPI) module is a
synchronous serial interface useful for communicating
with other peripheral or microcontroller devices. These
peripheral devices may be serial EEPROMs, shift reg-
isters, display drivers, A/D Converters, etc. The SPI
module is compatible with Motorola’s SPI and SIOP
interfaces.
The module supports operation in two buffer modes. In
Standard mode, data is shifted through a single serial
buffer. In Enhanced Buffer mode, data is shifted
through an 8-level FIFO buffer.
The module also supports a basic framed SPI protocol
while operating in either Master or Slave mode. A total
of four framed SPI configurations are supported.

PIC24FJ64GA004 FAMILY
The SPI serial interface consists of four pins:
• SDIx: Serial Data Input
• SDOx: Serial Data Output
• SCKx: Shift Clock Input or Output
• SSx: Active-Low Slave Select or Frame
The SPI module can be configured to operate using 2,
3 or 4 pins. In the 3-pin mode, SSx is not used. In the
2-pin mode, both SDOx and SSx are not used.
Block diagrams of the module in Standard and
Enhanced modes are shown in Figure 15-1 and
Figure 15-2.
Depending on the pin count, devices of the
PIC24FJ64GA004 family offer one or two SPI modules
on a single device.
Synchronization I/O Pulse
Note:
In this section, the SPI modules are
referred to together as SPIx or separately
as SPI1 and SPI2. Special Function Reg-
isters will follow a similar notation. For
example, SPIxCON1 or SPIxCON2 refers
to the control register for the SPI1 or SPI2
module.
