13.0
The Synchronous Serial Port (SSP) module is a serial
interface used to communicate with other peripheral or
microcontroller devices. These peripheral devices
may be serial EEPROMs, shift registers, display
drivers, A/D converters, etc. The SSP module can
operate in one of two modes:
• Serial Peripheral Interface (SPI)
• Inter-Integrated Circuit (I
Refer to Application Note AN578, “Use of the SSP
Module in the Multi-Master Environment” (DS00578).
13.1
This section contains register definitions and operational
characteristics of the SPI module.
The SPI mode allows 8 bits of data to be synchronously
transmitted and received simultaneously. To accomplish
communication, typically three pins are used:
• Serial Data Out (SDO)
• Serial Data In (SDI)
• Serial Clock (SCK)
Additionally, a fourth pin may be used when in a Slave
mode of operation:
• Slave Select (SS)

pin control enabled (SSPM<3:0> bits of
the SSPCON register = 0100), the SPI
module will reset if the SS pin is set to
V
CKE = 1, then the SS pin control must be
enabled.
pin control enabled (SSPM<3:0> bits of
the SSPCON register = 0100), the state
of the SS pin can affect the state read
back from the TRISC<4> bit. The
peripheral OE signal from the SSP
module into PORTC controls the state that
is read back from the TRISC<4> bit (see
Section 17.0
Specifications”
PORTC). If read-write-modify instructions,
such as BSF, are performed on the
TRISC register while the SS pin is high,
this will cause the TRISC<7> bit to be set,
thus disabling the SDO output.
