PIC16C6X
11.0 SYNCHRONOUS SERIAL PORT
(SSP) MODULE
11.1 SSP Module Overview
The Synchronous Serial Port (SSP) module is a serial
interface useful for communicating with other periph-
eral or microcontroller devices. These peripheral
devices may be Serial EEPROMs, shift registers, dis-
play drivers, A/D converters, etc. The SSP module can
operate in one of two modes:
• Serial Peripheral Interface (SPI)
• Inter-Integrated Circuit (I
2
C)
The SSP module in I
2
C mode works the same in all
PIC16C6X devices that have an SSP module. However
the SSP Module in SPI mode has differences between
the PIC16C66/67 and the other PIC16C6X devices.
The register definitions and operational description of
SPI mode has been split into two sections because of
the differences between the PIC16C66/67 and the
other PIC16C6X devices. The default reset values of
both the SPI modules is the same regardless of the
device:
