In Master mode, the overflow bit is not set since each new reception (and transmission) is initiated by writing to the SSPBUF register.
When enabled, these pins must be properly configured as input or output.
When enabled, the SDA and SCL pins must be configured as inputs.
SSPADD values of 0, 1 or 2 are not supported for I

SSPOV
A write to the SSPBUF register was attempted while the I
No collision
The SSPBUF 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 SSPBUF register is still holding the previous data. In case 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 overflow. In Master mode, the overflow bit is not set since each new reception (and transmission) is initiated by writing to the
SSPBUF register (must be cleared in software).
No overflow
A byte is received while the SSPBUF register is still holding the previous byte. SSPOV is a “don’t care” in Transmit mode
(must be cleared in software).
No overflow
Enables serial port and configures SCK, SDO, SDI and SS 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 SDA and SCL pins as the source of the serial port pins
