Each interrupt source other than the baud rate generator interrupt has an associated bit in
the I2CISTAT register, which clears automatically when software reads the register or
performs some other task such as reading or writing the data register.

received by the I
register. If the RDRF interrupt is not serviced prior to the completion of the next receive
byte, the I
is cleared to prevent receive overruns. A receive interrupt does not occur when a Slave
receives an address byte or for data bytes following a Slave address that did not match. An
exception is if the interactive receive mode (
which case receive interrupts occur for all receive address and data bytes in Slave mode.
Slave Address Match interrupts
Slave address match interrupts (
is in Slave mode and an address is received which matches the unique Slave address. The
General Call Address (0000_0000) and STARTBYTE (0000_0001) are recognized if the

register to determine if the transaction is a read or write transaction. The General Call
Address and STARTBYTE addresses are also distinguished by the

If configured using the
