Enabling SPI I/O
To enable the serial port the SSP Enable bit, SSPEN (SSPCON<5>), must be set. To reset or
reconfigure SPI mode, clear the SSPEN bit which re-initializes the SSPCON register, and then
set the SSPEN bit. 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 TRIS
register) appropriately programmed. That is:
• SDI must have the TRIS bit set
• SDO must have the TRIS bit cleared
• SCK (Master mode) must have the TRIS bit cleared
• SCK (Slave mode) must have the TRIS bit set
• SS must have the TRIS bit set
Any serial port function that is not desired may be overridden by programming the corresponding
data direction (TRIS) register to the opposite value. An example would be in master mode where
you are only sending data (to a display driver), then both SDI and SS could be used as general
purpose outputs by clearing their corresponding TRIS register bits.
