R = Readable bit

U = Unimplemented bit,
read as ‘0’
- n =Value at POR reset

bit0
bit 7:
WCOL: Write Collision Detect bit
1 = The SSPBUF register is written while it is still transmitting the previous word
(must be cleared in software)
0 = No collision
bit 6:
SSPOV: Receive Overow Indicator bit
In SPI mode
1 = A new byte is received while the SSPBUF register is still holding the previous data. In case of overow,
the data in SSPSR is lost. Overow can only occur in slave mode. The user must read the SSPBUF, even
if only transmitting data, to avoid setting overow. In master mode the overow bit is not set since each
new reception (and transmission) is initiated by writing to the SSPBUF register.
0 = No overow
In I2C mode
1 = A byte is received while the SSPBUF register is still holding the previous byte. SSPOV is a "don’t care"
in transmit mode. SSPOV must be cleared in software in either mode.
0 = No overow
bit 5:
SSPEN: Synchronous Serial Port Enable bit
In SPI mode
1 = Enables serial port and congures SCK, SDO, and SDI as serial port pins
0 = Disables serial port and congures these pins as I/O port pins
In I2C mode
1 = Enables the serial port and congures the SDA and SCL pins as serial port pins
0 = Disables serial port and congures these pins as I/O port pins
In both modes, when enabled, these pins must be properly congured as input or output.
bit 4:
CKP: Clock Polarity Select bit
In SPI mode
1 = Idle state for clock is a high level
0 = Idle state for clock is a low level
In I2C mode
SCK release control
1 = Enable clock
0 = Holds clock low (clock stretch) (Used to ensure data setup time)
bit 3-0: SSPM3:SSPM0: Synchronous Serial Port Mode Select bits
0000
= SPI master mode, clock = FOSC/4
0001
= SPI master mode, clock = FOSC/16
0010
= SPI master mode, clock = FOSC/64
0011
= SPI master mode, clock = TMR2 output/2
0100
= SPI slave mode, clock = SCK pin. SS pin control enabled.
0101
= SPI slave mode, clock = SCK pin. SS pin control disabled. SS can be used as I/O pin
0110
= I2C slave mode, 7-bit address
0111
= I2C slave mode, 10-bit address
1011
= I2C Firmware controlled master mode (slave idle)
1110
= I2C slave mode, 7-bit address with start and stop bit interrupts enabled
1111
= I2C slave mode, 10-bit address with start and stop bit interrupts enabled
