Bit 7 WCOL: Write collision detector register flag.
1 = The I2CBUF register is written while it is still transmitting the previous data.
0 = No write collision is happened. This register should be clear in software.
Bit 6 I2COV: Receive overflow detector register flag
1 = A byte is received while theI2CBUF is still holding the previous data.
0 = No receive overflow is happened. This register should be clear in software
Bit 5 I2CEN: I2C module enable flag
1 = I2C module is enabled.
0 = I2C module is disabled.
Bit 4 CKP: SCK signal control register
1 = SCK pin is enabled.
0 = SCK pin is disabled and hold to low.
