I2CxCON and I2CxSTAT are control and status
registers, respectively. The I2CxCON register is
readable and writable. The lower six bits of I2CxSTAT
are read-only. The remaining bits of the I2CSTAT are
read/write.
• I2CxRSR is the shift register used for shifting data
• I2CxRCV is the receive buffer and the register to
• I2CxTRN is the transmit register to which bytes
• The I2CxADD register holds the slave address
• A status bit, ADD10, indicates 10-bit Address
• I2CxBRG acts as the Baud Rate Generator
In receive operations, I2CxRSR and I2CxRCV together
form a double-buffered receiver. When I2CxRSR
receives a complete byte, it is transferred to I2CxRCV,
and an interrupt pulse is generated.

A separate interrupt is generated for all I
conditions.

In I
Generator (BRG) is located in the I2CxBRG register.
When the BRG is loaded with this value, the BRG
counts down to zero and stops until another reload has
taken place. If clock arbitration is taking place, for
example, the BRG is reloaded when the SCLx pin is
sampled high.
