______________________________________________________________________________________
Available addresses depend on the hardware connec-
tions of pins A2, A1, and A0 as shown in Table 1.
The last bit following the slave address bit A0 on an I2C
command defines the operation to be performed. When
the last bit sets to logic 1, a read is selected while logic
0 selects a write operation.
Register Map (MAX7357/MAX7358)
The MAX7357 and MAX7358 have 7 registers (shown in
Table 2) that can be accessed through the I2C bus. The
MAX7357 powers up with all of these registers accessi-
ble. The initial register address counter is at 0x00. The
MAX7358 powers up in basic mode with only the switch
control register available. Writing to a MAX7358
changes only the contents of the switch control register.
By sending a unique I2C sequence to the MAX7358, all
7 registers become available.
Register Access Protocol (MAX7356)
Only the MAX7356 device address is required to gain
access to its registers. A typical I2C command to com-
municate with the MAX7356 starts with its device
address followed directly by data bytes.
