SERIAL PORT (MSSP)

MODULE

21.1 MSSP Module Overview

The Master Synchronous Serial Port (MSSPx) 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 MSSPx module

can operate in one of two modes:

• Serial Peripheral Interface (SPI)

• Inter-Integrated Circuit (I2C™)

The SPI interface supports the following modes and

features:

• Master mode

• Slave mode

• Clock Parity

• Slave Select Synchronization (Slave mode only)

• Daisy-chain connection of slave devices

Figure 21-1 is a block diagram of the SPI interface

module.
