21.5
There are six interrupt requests in this module; transmit data empty, transmit end, receive data full,
NACK detection, STOP recognition, and arbitration lost. Table 21.3 shows the contents of each
interrupt request.
Table 21.3 Interrupt Requests
When one of the interrupt conditions in table 21.3 is 1 and the I bit in CCR is 0, the CPU executes
interrupt exception handling. Clear the interrupt sources during interrupt exception handling. Note
that the TDRE and TEND bits are automatically cleared to 0 by writing data to ICDRT, and the
RDRF bit is cleared to 0 by reading ICDRR. In particular, the TDRE bit can be set again at the
same time as data are for transmission written to ICDRT, and 1 extra byte can be transmitted if the
TDRE is again cleared to 0.
