SYNCHRONOUS SERIAL

PORT (SSP) MODULE

11.1

SSP Module Overview

The Synchronous Serial Port (SSP) module is a serial

interface useful for communicating with other periph-

eral or microcontroller devices. These peripheral

devices may be Serial EEPROMs, shift registers, dis-

play drivers, A/D converters, etc. The SSP module can

operate in one of two modes:

• Serial Peripheral Interface (SPI)

• Inter-Integrated Circuit (I2C)

The SSP module in I2C mode works the same in all

PIC16C7X devices that have an SSP module. However

the SSP Module in SPI mode has differences between

the PIC16C76/77 and the other PIC16C7X devices.

The register deﬁnitions and operational description of

SPI mode has been split into two sections because of

the differences between the PIC16C76/77 and the

other PIC16C7X devices. The default reset values of

both the SPI modules is the same regardless of the

device:

11.2 SPI Mode for PIC16C72/73/73A/74/74A ..........78

11.3 SPI Mode for PIC16C76/77..............................83

11.4 I2C™ Overview ................................................89

11.5 SSP I2C Operation...........................................93

Refer to Application Note AN578,

“Use of the SSP

Module in the I 2C Multi-Master Environment.”
