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.
