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 (I
The I
hardware:
• Master mode
• Multi-Master mode
• Slave mode

The SPI mode allows 8 bits of data to be synchronously
transmitted and received simultaneously. All four
modes
communication, typically three pins are used:
• Serial Data Out – SDO
• Serial Data In – SDI
• Serial Clock – SCK
Additionally, a fourth pin may be used when in a Slave
mode of operation:
• Slave Select – SS
Figure 14-1 shows the block diagram of the MSSP
module when operating in SPI mode.
