Section 15 I
15.5
There are six interrupt requests in this module; transmit data empty, transmit end, receive data full,
NACK receive, STOP recognition, and arbitration lost/overrun error. Table 15.3 shows the
contents of each interrupt request.
Table 15.3 Interrupt Requests
When interrupt conditions described in table 15.3 are 1 and the I bit in CCR is 0, the CPU
executes an interrupt exception processing. Interrupt sources should be cleared in the exception
processing. TDRE and TEND are automatically cleared to 0 by writing the transmit data to
ICDRT. RDRF are automatically cleared to 0 by reading ICDRR. TDRE is set to 1 again at the
same time when transmit data is written to ICDRT. When TDRE is cleared to 0, then an excessive
data of one byte may be transmitted.
