AA : Assert Acknowledge Control Bit\n
bits : 2 - 2 (1 bit)
access : read-write
SI : I2C Interrupt Flag\nWhen a new I2C state is present in the I2CSTATUS register, the SI flag is set by hardware, and if bit EI (I2CON [7]) is set, the I2C interrupt is requested. SI must be cleared by software. Clear SI is by writing 1 to this bit.
bits : 3 - 3 (1 bit)
access : read-write
STO : I2C STOP Control Bit
In Master mode, setting STO to transmit a STOP condition to bus then I2C hardware will check the bus condition if a STOP condition is detected this bit will be cleared by hardware automatically. In a Slave mode, setting STO resets I2C hardware to the defined not addressed Slave mode. This means it is NO LONGER in the slave receiver mode to receive data from the master transmit device.
bits : 4 - 4 (1 bit)
access : read-write
STA : I2C START Control Bit\nSetting STA to logic 1 to enter Master mode, the I2C hardware sends a START or repeat START condition to bus when the bus is free.

ENTI : Time-out Counter Enable/Disable\nWhen Enabled, the 14-bit time-out counter will start counting when SI is cleared. Setting the flag SI to high will reset counter and re-start counting up after SI is cleared.

I2CADM : I2C Address Mask Register\nI2C bus controllers support multiple address recognition with four address mask register. When the bit in the address mask register is set to one, it means the received corresponding address bit is don't-care. If the bit is set to zero, it means the received corresponding register bit should be exact the same as address register.
