SYNCHRONOUS SERIAL PORT

(SSP) MODULE

8.1

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

PIC16C72 series devices that have an SSP module.

However the SSP Module in SPI mode has differences

between the PIC16C72 and the PIC16CR72 device.

The register definitions and operational description of

SPI mode has been split into two sections because of

the differences between the PIC16C72 and the

PIC16CR72 device. The default reset values of both

the SPI modules is the same regardless of the device:

8.2

SPI Mode for PIC16C72 .................................. 40

8.3

SPI Mode for PIC16CR72 ............................... 43

8.4

SSP I2C Operation .......................................... 47

For an I2C Overview, refer to the PIC® Mid-Range MCU

Reference Manual (DS33023). Also, refer to Applica-

tion Note AN578,

“Use of the SSP Module in the I 2C

Multi-Master Environment.”
