Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

bit 6
bit 5
bit 4
bit 3-0
Note 1:
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
SSPOV: Receive Overflow Indicator bit
1 = A new byte is received while the SSPBUF register is still holding the previous data. In case of
overflow, the data in SSPSR is lost. Overflow can only occur in Slave mode. The user must read
the SSPBUF, even if only transmitting data, to avoid setting overflow. In Master mode, the over-
flow bit is not set since each new reception (and transmission) is initiated by writing to the
SSPBUF register.
0 = No overflow
SSPEN: Synchronous Serial Port Enable bit
1 = Enables serial port and configures SCK, SDO and SDI as serial port pins(1)
0 = Disables serial port and configures these pins as I/O port pins
CKP: Clock Polarity Select bit
1 = Idle state for clock is a high level
0 = Idle state for clock is a low level
SSPM<3:0>: 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.
When enabled, these pins must be properly configured as input or output.
