17.0 MASTER SYNCHRONOUS
SERIAL PORT (MSSP)
MODULE
17.1
Master SSP (MSSP) Module
Overview
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, dis-
play drivers, A/D converters, etc. The MSSP module
can operate in one of two modes:
Serial Peripheral Interface (SPI)
Inter-Integrated Circuit (I2C)
- Full Master mode
- Slave mode (with general address call)
The I2C interface supports the following modes in
hardware:
Master mode
Multi-Master mode
Slave mode
17.2
Control Registers
The MSSP module has three associated registers.
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 I2C mode.
Additional details are provided under the individual
sections.
17.3
SPI Mode
The SPI mode allows 8 bits of data to be synchronously
transmitted and received, simultaneously. All four
modes of SPI are supported. To accomplish
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/LVDIN/C2OUT
Register 17-1 shows the block diagram of the MSSP
module when operating in SPI mode.
