MAX13325/MAX13326
START and STOP Conditions
A master device initiates communication by issuing
a START condition, which is a high-to-low transition
on SDA with SCL high. A START condition from the
master signals the beginning of a transmission to the
MAX13325/MAX13326. The master terminates transmis-
sion by a STOP condition (see the Acknowledge Bit
section). A STOP condition is a low-to-high transition
on SDA while SCL is high (Figure 3). The STOP condi-
tion frees the bus. If a Repeated START condition is
generated instead of a STOP condition, the bus remains
active. When a STOP condition or incorrect slave ID is
detected, the device internally disconnects SCL from the
serial interface until the next START or Repeated START
condition, minimizing digital noise and feedthrough.
Acknowledge Bit
The acknowledge (ACK) bit is a clocked 9th bit that
the MAX13325/MAX13326 use to handshake receipt of
each byte of data when in write mode. The MAX13325/
MAX13326 pull down SDA during the entire master-
generated 9th clock pulse if the previous byte is suc-
cessfully received (see Figure 4). Monitoring ACK
allows for detection of unsuccessful data transfers. An
unsuccessful data transfer occurs if a receiving device
is busy or if a system fault has occurred. In the event
