I2C Registers and
Bit Descriptions
Twenty-eight internal registers program and report the
status of the MAX9851/MAX9853. Table 8 lists all of the
registers, their addresses, and power-on-reset states.
Registers 0x00 and 0x01 are read-only while all of the
other registers are read/write. Registers 0x1C–0x1F are
reserved for factory testing. Write zeros to all unused
bits in the register table when updating the register,
unless otherwise noted.
Slave Address
The MAX9851/MAX9853 are preprogrammed with a
slave address of 0x20 or 0010000. The address is
defined as the 7 most significant bits (MSBs) followed
by the read/write bit. Set the read/write bit to 1 to con-
figure the MAX9851/MAX9853 to read mode. Set the
read/write bit to 0 to configure the MAX9851/
MAX9853 to write mode. The address is the first byte of
information sent to the MAX9851/MAX9853 after the
START condition.
