In Master mode, the overflow bit is not set since each new reception (and transmission) is initiated by writing to the SSPxBUF register.
When enabled, these pins must be properly configured as input or output.
When enabled, the SDAx and SCLx pins must be configured as inputs.
SSPxADD values of 0, 1 or 2 are not supported for I
SSPxADD value of ‘0’ is not supported. Use SSPxM = 0000 instead.

A write to the SSPxBUF register was attempted while the I
No collision
The SSPxBUF register is written while it is still transmitting the previous word (must be cleared in software)
No collision
A new byte is received while the SSPxBUF register is still holding the previous data. In case of overflow, the data in SSPxSR is lost.
Overflow can only occur in Slave mode. In Slave mode, the user must read the SSPxBUF, 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
SSPxBUF register (must be cleared in software).
No overflow
A byte is received while the SSPxBUF register is still holding the previous byte. SSPxOV is a “don’t care” in Transmit mode
(must be cleared in software).
No overflow
Enables serial port and configures SCKx, SDOx, SDIx and SSx as the source of the serial port pins
Disables serial port and configures these pins as I/O port pins
Enables the serial port and configures the SDAx and SCLx pins as the source of the serial port pins
Disables serial port and configures these pins as I/O port pins
