19.0
19.1
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
19.2
The MSSP module has three associated control regis-
ters. These include a status register (SSPSTAT) and
two control registers (SSPCON1 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.

19.3
The SPI mode allows 8 bits of data to be synchronously
transmitted and received simultaneously. All four
modes of the SPI are supported. To accomplish
communication, typically three pins are used:
• Serial Data Out (SDO) – RC7/RX/DT/SDO
• Serial Data In (SDI) – RB0/AN12/INT0/FLT0/SDI/SDA
• Serial Clock (SCK) – RB1/AN10/INT1/SCK/SCL
Additionally, a fourth pin may be used when in a Slave
mode of operation:
• Slave Select (SS) – RA5/AN4/SS/HLVDIN/C2OUT
Figure 19-1 shows the block diagram of the MSSP
module when operating in SPI mode.
