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 serial EEPROMs, shift registers,
display drivers, A/D Converters, etc. The MSSP
module can operate in one 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
All members of the PIC18F87K90 family have two
MSSP modules, designated as MSSP1 and MSSP2.
Each module operates independently of the other.
21.2
Each MSSP module has three associated control regis-
ters. These include a status register (SSPxSTAT) and
two control registers (SSPxCON1 and SSPxCON2). 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.

Overview
Control Registers
Throughout this section, generic refer-
ences to an MSSP module in any of its
operating modes may be interpreted as
being equally applicable to MSSP1 or
MSSP2. Register names and module I/O
signals use the generic designator ‘x’ to
indicate the use of a numeral to distinguish
a particular module when required. Control
bit names are not individuated.
In devices with more than one MSSP
module, it is very important to pay close
attention to SSPxCON register names.

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 (SDOx) – RC5/SDO1/SEG12 or
• Serial Data In (SDIx) – RC4/SDI1/SDA1/SEG16
• Serial Clock (SCKx) – RC3/SCK1/SCL1/SEG17
Additionally, a fourth pin may be used when in a Slave
mode of operation:
• Slave Select (SSx) – RF7/AN5/SS1/SEG25 or

module when operating in SPI mode.
