15.3
The SPI mode allows 8 bits of data to be synchronously
transmitted and received, simultaneously. All four
modes of SPI are supported. To accomplish communi-
cation, typically three pins are used:
• Serial Data Out (SDO) - RC5/SDO
• Serial Data In (SDI) - RC4/SDI/SDA
• Serial Clock (SCK) - RC3/SCK/SCL/LVOIN
Additionally, a fourth pin may be used when in any
Slave mode of operation:
• Slave Select (SS) - RA5/SS/AN4
15.3.1
When initializing the SPI, several options need to be
specified. This is done by programming the appropriate
control bits SSPCON1<5:0> and SSPSTAT<7:6>.
These control bits allow the following to be specified:
• Master mode (SCK is the clock output)
• Slave mode (SCK is the clock input)
• Clock polarity (Idle state of SCK)
• Data input sample phase (middle or end of data
• Clock edge (output data on rising/falling edge of
• Clock rate (Master mode only)
• Slave Select mode (Slave mode only)

module, when in SPI mode.
