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
An overview of I
tion on the SSP module can be found in the PICmicro™
Mid-Range
(DS33023).

Module in the I
10.2
This section contains register definitions and opera-
tional characteristics of the SPI module.
SPI mode allows 8 bits of data to be synchronously
transmitted and received simultaneously. To accom-
plish communication, typically three pins are used:
• Serial Data Out (SDO) RC5/SDO
• Serial Data In (SDI) RC4/SDI/SDA
• Serial Clock (SCK) RC3/SCK/SCL
Additionally, a fourth pin may be used when in a Slave
mode of operation:
• Slave Select (SS) RA5/SS/AN4
When initializing the SPI, several options need to be
specified. This is done by programming the appropriate
control bits in the SSPCON register (SSPCON<5:0>)
and SSPSTAT<7:6>. These control bits allow the fol-
lowing to be specified:
• Master mode (SCK is the clock output)
• Slave mode (SCK is the clock input)
• Clock Polarity (Idle state of SCK)
• Clock edge (output data on rising/falling edge of
• Clock Rate (Master mode only)
• Slave Select mode (Slave mode only)

FIGURE 10-1:
To enable the serial port, SSP enable bit, SSPEN
(SSPCON<5>) must be set. To reset or reconfigure SPI
mode, clear bit SSPEN, re-initialize the SSPCON reg-
ister, and then set bit SSPEN. This configures the SDI,
SDO, SCK, and SS pins as serial port pins. For the pins
to behave as the serial port function, they must have
their data direction bits (in the TRISC register) appro-
priately programmed. That is:
• SDI must have TRISC<4> set
• SDO must have TRISC<5> cleared
• SCK (Master mode) must have TRISC<3> cleared
• SCK (Slave mode) must have TRISC<3> set
• SS must have TRISA<5> set
• ADCON1 must configure RA5 as a digital I/O pin.

pin control enabled (SSPCON<3:0> =

pin is set to V

enabled.
