x = unknown, u = unchanged, - = unimplemented, read as ‘0’. Shaded cells are not used by the SSP in SPI™ mode.
This bit is only implemented on the PIC16F88. The bit will read ‘0’ on the PIC16F87.

To enable the serial port, SSP Enable bit, SSPEN
(SSPCON<5>), must be set. To reset or reconfigure
SPI mode, clear bit SSPEN, reinitialize the SSPCON
register 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 TRISB register)
appropriately programmed. That is:
• SDI must have TRISB<1> set
• SDO must have TRISB<2> cleared
• SCK (Master mode) must have TRISB<4>
• SCK (Slave mode) must have TRISB<4> set
• SS must have TRISB<5> set
cleared

2: If the SPI is used in Slave mode with
control enabled (SSPCON<3:0> = 0100),
the SPI module will reset if the SS pin is
set to V
CKE = 1, then the SS pin control must be
enabled.
