After generating a START condition, the bus master
transmits the slave address consisting of a 7-bit device
code (0b0101111 or 5Eh) for the MAX8738. Since the
MAX8738 is a write-only device, the eighth bit of the
slave address is zero. The MAX8738 monitors the bus
for its corresponding slave address continuously. It
generates an acknowledge bit when it recognizes its
address.
The state of the data line represents valid data when,
after a START condition, the data line is stable for the
duration of the HIGH period of the clock signal. The
data on the line must be changed during the LOW peri-
od of the clock signal. There is one clock pulse per bit
of data.
Each receiving device, when addressed, is obliged to
generate an acknowledge after the reception of each

byte. The master device must generate an extra clock
pulse that is associated with this acknowledge bit. The
device that acknowledges has to pull down the SDA
line during the acknowledge clock pulse so that the
SDA line is stable LOW during the HIGH period of the
acknowledge-related clock pulse. Of course, setup and
hold times must be taken into account. See Figure 7.
The MAX8738 does not acknowledge the program
EEPROM command (AAh) if HV is below 15.6V (typ) or
if the MAX8738 is not in program mode.
The MAX8738 does not acknowledge any command
while an internal programming cycle is in progress.
Once the internally timed EEPROM write cycle has
started, acknowledge polling can be initiated. This
involves repeatedly sending a 55h command. Only if
the internal write cycle has completed does the
MAX8738 acknowledge the command.
