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,
display drivers, A/D converters, etc. The MSSPx
module can operate in one of two modes:
• Serial Peripheral Interface (SPI)
• Inter-Integrated Circuit (I
