C Interrupts
The I
request signal to the interrupt controller. If the I
interrupt is determined by which bits are set in the I2CISTAT register. If the I
controller is disabled, the BRG controller can be used to generate general-purpose timer
interrupts.
Each interrupt source, other than the baud rate generator interrupt, features an associated
bit in the I2CISTAT register that clears automatically when software reads the register or
performs another task, such as reading/writing the data register.
Transmit Interrupts

Receive Interrupts
Receive interrupts (
received by the I
register. If the RDRF interrupt is not serviced prior to the completion of the next Receive
byte, the I
RDRF
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 (
register, in which case Receive interrupts occur for all Receive address and data bytes in
SLAVE mode.
Slave Address Match Interrupts
