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:
鈥?Serial Peripheral Interface (SPI)
鈥?Inter-Integrated Circuit (I
2
C)
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 I
2
C modes of operation.
