WCOL: Write Collision Detect bit
Master Mode:
1 = A write to the SSPBUF register was attempted while the I
0 = No collision
Slave Mode:
1 = The SSPBUF register is written while it is still transmitting the previous word
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 a
0 = No overflow
SSPEN: Synchronous Serial Port Enable bit
In both modes, when enabled, these pins must be properly configured as input or output.
In SPI mode:
1 = Enables serial port and configures SCK, SDO, SDI, and SS as the source of the serial
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 the source of the
0 = Disables serial port and configures these pins as I/O port pins
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 I
SCK release control
1 = Enable clock
0 = Holds clock low (clock stretch) (Used to ensure data setup time)

of overflow, the data in SSPSR is lost. Overflow can only occur in slave mode. In slave
mode, the user must read the SSPBUF, even if only transmitting data, to avoid setting over-
flow. In master mode the overflow bit is not set since each new reception (and transmission)
is initiated by writing to the SSPBUF register.
