9.1
The Master Synchronous Serial Port (MSSP) module is
a serial interface, useful for communicating with other
peripheral or microcontroller devices. These peripheral
devices may be serial EEPROMs, shift registers,
display drivers, A/D converters, etc. The MSSP module
can operate in one of two modes:
• Serial Peripheral Interface (SPI)
• Inter-Integrated Circuit (I
The I
hardware:
• Master mode
• Multi-Master mode
• Slave mode
9.2
The MSSP module has three associated registers.
These include a status register (SSPSTAT) and two
control registers (SSPCON and SSPCON2). The use
of these registers and their individual configuration bits
differ significantly, depending on whether the MSSP
module is operated in SPI or I
Additional details are provided under the individual
sections.
9.3
The SPI mode allows 8 bits of data to be synchronously
transmitted and received simultaneously. All four
modes
communication, typically three pins are used:
• Serial Data Out (SDO) – RC5/SDO
• Serial Data In (SDI) – RC4/SDI/SDA
• Serial Clock (SCK) – RC3/SCK/SCL
Additionally, a fourth pin may be used when in a Slave
mode of operation:
• Slave Select (SS) – RA5/AN4/SS/C2OUT
Figure 9-1 shows the block diagram of the MSSP
module when operating in SPI mode.

When the SPI is in Slave mode with SS pin
control enabled (SSPCON<3:0> = 0100),
the state of the SS pin can affect the state
read back from the TRISC<5> bit. The
Peripheral OE signal from the SSP mod-
ule in PORTC controls the state that is
read back from the TRISC<5> bit (see
Section 4.3 “PORTC and the TRISC
Register” for information on PORTC). If
Read-Modify-Write instructions, such as
BSF, are performed on the TRISC register
while the SS pin is high, this will cause the
TRISC<5> bit to be set, thus disabling the
SDO output.
