29 MSSP - Host Synchronous Serial Port Module

The Host 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, display drivers, A/D converters, etc. The MSSP module can operate in one of two modes:

Serial Peripheral Interface (SPI)
Inter-Integrated Circuit (I²C)

The SPI interface can operate in Host or Client mode and supports the following features:

Selectable Clock Parity
Client Select Synchronization (Client Mode Only)
Daisy-Chain Connection of Client Devices

The I²C interface can operate in Host or Client mode and supports the following modes and features:

Byte NACKing (Client Mode)
Limited Multi-Host Support
7-Bit and 10-Bit Addressing
Start and Stop Interrupts
Interrupt Masking
Clock Stretching
Bus Collision Detection
General Call Address Matching
Address Masking
Address Hold and Data Hold Modes
Selectable SDA Hold Times
