21.0
21.1
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 devices such as serial EEPROMs, shift
registers, display drivers and A/D Converters. The
MSSP module can operate in either of two modes:
• Serial Peripheral Interface (SPI)
• Inter-Integrated Circuit (I
The I
hardware:
• Master mode
• Multi-Master mode
• Slave mode with 5-bit and 7-bit address masking
21.2
The MSSP module has three associated control regis-
ters. These include a status register (SSPSTAT) and
two control registers (SSPCON1 and SSPCON2). The
use of these registers and their individual configuration
bits differ significantly depending on whether the MSSP
module is operated in SPI or I
Additional details are provided under the individual
sections.
21.3
The SPI mode allows 8 bits of data to be synchronously
transmitted and received simultaneously. All four
modes
communication, typically three pins are used:
• Serial Data Out (SDO) – RC5/SDO
• Serial Data In (SDI) – RC4/SDA/SDI
• Serial Clock (SCK) – RC3/REF0/SCL/SCK
Additionally, a fourth pin may be used when in a Slave
mode of operation:
• Slave Select (SS) – RA5/AN4/C2INB/
