bit 7
WCOL: Write Collision Detect bit
Master mode:
1 = A write to SSPBUF was attempted while the I2C conditions were not valid
0 = No collision
Slave mode:
1 = SSPBUF register is written while still transmitting the previous word (must be cleared in
0 = No collision
In SPI mode:
1 = A new byte is received while SSPBUF holds previous data. Data in SSPSR is lost on overflow. In Slave
0 = No overflow
In I
1 = A byte is received while the SSPBUF is holding the previous byte. SSPOV is a "don’t care" in Transmit
0 = No overflow
SSPEN: Synchronous Serial Port Enable bit
In SPI mode,
When enabled, these pins must be properly configured as input or output
1 = Enables serial port and configures SCK, SDO, SDI, and SS as the source of the serial port pins
0 = Disables serial port and configures these pins as I/O port pins
In I
When enabled, these pins must be properly configured as input or output
1 = Enables the serial port and configures the SDA and SCL pins as the source of the 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 = 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.)
In I
Unused in this mode

0000 = SPI Master mode, clock = F
0001 = SPI Master mode, clock = F
0010 = SPI Master mode, clock = F
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.
