Introduction
The Master Synchronous Serial Port (MSSP) module is a serial interface useful for communicat-
ing 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 (I
