15.0
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
Figure 15-1 shows a block diagram for the SPI mode,
while Figure 15-2 and Figure 15-3 show the block
diagrams for the two different I
