address does not match. Similarly, if the start condition or address is transmitted from the
master device in slave transmit mode (TRS = 1), the IRIC flag may be set after the ICDRE flag
is set and 1 received as the acknowledge bit value (ACKB = 1), thus causing an interrupt
source even when the address does not match.
To use the I

of a series of transmit operation, clear the ACKE bit in ICCR once to initialize the ACKB
bit to 0.
Complete transmit operation by the procedure shown in figure 13.23, in order to switch
from slave transmit mode to slave receive mode.
