MASTER SYNCHRONOUS

SERIAL PORT (MSSP)

MODULE

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)

Figure 9-1 shows a block diagram for the SPI mode,

while Figure 9-5 and Figure 9-9 show the block dia-

grams for the two different I2C modes of operation.

The Application Note AN734, “Using the PICmicro®

SSP for Slave I2CTM Communication” describes the

slave

operation

the

MSSP

module

the

PIC16F87X devices. AN735, “Using the PICmicro®

MSSP Module for I2CTM Communications” describes

the master operation of the MSSP module on the

PIC16F87X devices.
