PIC18F46J50 FAMILY
18.2
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 differ significantly depending on whether the
MSSP module is operated in SPI or I
Additional details are provided under the individual
sections.
18.3
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 18.4 “SPI DMA Module”.
To accomplish communication, typically three pins are
used:
• Serial Data Out (SDOx) –
• Serial Data In (SDIx) –
• Serial Clock (SCKx) –
Additionally, a fourth pin may be used when in a Slave
mode of operation:
• Slave Select (SSx) – RA5/AN4/SS1/
Figure 18-1 depicts the block diagram of the MSSP
module when operating in SPI mode.

Control Registers
SPI Mode
In devices with more than one MSSP
module, it is very important to pay close
attention to the SSPxCON register names.
SSP1CON1 and
different operational aspects of the same
module,
SSP2CON1 control the same features for
two different modules.
