When enabled, the SDA and SCL pins must be properly configured as input or output.
Bit combinations not specifically listed here are either reserved or implemented in SPI mode only.
WCOL: Write Collision Detect bit
In Master Transmit mode:
1 = A write to the SSPBUF register was attempted while the I
0 = No collision
In Slave Transmit mode:
1 = The SSPBUF register is written while it is still transmitting the previous word (must be cleared in
0 = No collision
In Receive mode (Master or Slave modes):
This is a “don’t care” bit.
SSPOV: Receive Overflow Indicator bit
In Receive mode:
1 = A byte is received while the SSPBUF register is still holding the previous byte (must be cleared in
0 = No overflow
In Transmit mode:
This is a “don’t care” bit in Transmit mode.
SSPEN: Master Synchronous Serial Port Enable bit
1 = Enables the serial port and configures the SDA and SCL pins as the serial port pins
0 = Disables serial port and configures these pins as I/O port pins
CKP: SCK Release Control bit
In Slave mode:
1 = Releases clock
0 = Holds clock low (clock stretch), used to ensure data setup time
In Master mode:
Unused in this mode.
