20.2
Each MSSP module has three associated control
and two control registers (SSPxCON1 and SSPxCON2).
The use of these registers and their individual Configura-
tion bits differs significantly depending on whether the
MSSP module is operated in SPI or I
Additional details are provided under the individual
sections.
20.3
The SPI mode allows 8 bits of data to be synchronously
transmitted and received simultaneously. All four
modes of SPI are supported.
When MSSP2 is used in SPI mode, it can optionally be
configured to work with the SPI DMA submodule
described in Section 20.4 “SPI DMA Module”.
To accomplish communication, typically three pins are
used:
• Serial Data Out (SDOx) – RC5/SDO1/RP16 or
• Serial Data In (SDIx) – RC4/SDI1/SDA1/RP15 or
• Serial Clock (SCKx) – RC3/SCK1/SCL1/RP14 or
Additionally, a fourth pin may be used when in a Slave
mode of operation:
• Slave Select (SSx) – RA5/AN4/C1INC/SS1/
Figure 20-1 depicts the block diagram of the MSSP
module when operating in SPI mode.

In devices with more than one MSSP
module, it is very important to pay close
attention to the SSPxCON register names.
