Message Format
Write to the MAX16805/MAX16806 by transmitting the
Table 2. Registers Address
device’s slave address with R/ W , 8th bit set to zero fol-
lowed by at least 1 byte of information ( Figure 7). The
first byte of information is the command byte. The bytes
received after the command byte are the data bytes.
The first data byte goes into the internal register as
selected by the command byte ( Figure 8). If there is
more than one data byte, the MAX16805/MAX16806
auto-increment to the next register address locations to
write the subsequent data bytes. The MAX16805/
MAX16806 auto-increment up to the register address
0x05, EEPROM Content Transfer register.
A read operation is performed as follows:
After the START condition (S), a 7-bit slave ID is sent
followed by an 8th bit (R/ W ) set to zero. A register
address is then sent to specify the address location
from which the read has to take place. To complete a
read operation, the master needs to generate a repeat-
