SSPCON: SYNCHRONOUS SERIAL PORT CONTROL REGISTER (ADDRESS 14h)
Legend:
R = Readable bit
-n = Value at POR
WCOL: Write Collision Detect bit
1 = An attempt to write the SSPBUF register failed because the SSP module is busy
0 = No collision
SSPOV: Receive Overflow Indicator bit
In SPI mode:
1 = A new byte is received while the SSPBUF register is still holding the previous data. In case
0 = No overflow
In I
1 = A byte is received while the SSPBUF register is still holding the previous byte. SSPOV is
0 = No overflow
SSPEN: Synchronous Serial Port Enable bit
In SPI mode:
1 = Enables serial port and configures SCK, SDO and SDI as serial port pins
0 = Disables serial port and configures these pins as I/O port pins
In I
1 = Enables the serial port and configures the SDA and SCL pins as serial port pins
0 = Disables serial port and configures these pins as I/O port pins
CKP: Clock Polarity Select bit
In SPI mode:
1 = Transmit happens on falling edge, receive on rising edge. Idle state for clock is a high level.
0 = Transmit happens on rising edge, receive on falling edge. Idle state for clock is a low level.
In I
SCK release control
1 = Enable clock
0 = Holds clock low (clock stretch). (Used to ensure data setup time.)
SSPM<3:0>: Synchronous Serial Port Mode Select bits
0000 = SPI Master mode, clock = OSC/4
0001 = SPI Master mode, clock = OSC/16
0010 = SPI Master mode, clock = OSC/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.

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 overflow bit is not set since each new reception (and transmission) is initiated
by writing to the SSPBUF register.
