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 operation of the module in SPI mode is discussed
in greater detail in Section 9.1. The operations of the
module in the the various I

The MSSP module is controlled by three special func-
tion registers:
• SSPSTAT
• SSPCON
• SSPCON2
The SSPSTAT and SSPCON registers are used in both
SPI and I
ent functions depending on the mode selected. The
SSPCON2 register, on the other hand, is associated
only with I
