Operation
SPI Mode
The SPI mode allows 8-bits of data to be synchronously transmitted and received simulta-
neously. All four modes of SPI are supported, as well as Microwire™ (sample edge) when the
SPI is in the master mode.
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)
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 following 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 SCK)
• Data Input Sample Phase
• Clock Rate (Master mode only)
• Slave Select Mode (Slave mode only)
