MASTER SYNCHRONOUS
SERIAL PORT (MSSP) MODULE
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 (I2C)
Figure 9-1 shows a block diagram for the SPI mode,
while Figure 9-5 and Figure 9-9 show the block dia-
grams for the two different I2C modes of operation.
