The MAX5550 recognizes a STOP condition at any point
during transmission except if a STOP condition occurs in
the same high pulse as a START condition (Figure 4).
This condition is not allowed in the I

Successful data transfers are acknowledged with an
acknowledge bit (ACK). Both the master and the
MAX5550 (slave) generate acknowledge bits. To gen-
erate an acknowledge, the receiving device must pull
SDA low before the rising edge of the acknowledge-
related clock pulse (ninth pulse) and keep it low during
the high period of the clock pulse (Figure 5).
Monitoring the acknowledge bits allows for detection of
unsuccessful data transfers. An unsuccessful data
transfer happens if a receiving device is busy or if a
system fault has occurred. In the event of an unsuc-
cessful data transfer, the master should reattempt com-
munication at a later time.
