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