SMBus Commands
The MAX8709B registers are accessible through several
different redundant commands (i.e., the command byte
in the read-byte and write-byte protocols), which can
be used to read or write the brightness, SHMD, status,
or ID registers.
Table 3 summarizes the command byte ’s register
assignments, as well as each register’s power-on state.
The MAX8709B also supports the receive-byte protocol
for quicker data transfers. This protocol accesses the
register configuration pointed to by the last command
byte. Immediately after power-up, the data byte
returned by the receive-byte protocol is the inverted
contents of the brightness register, left justified
(i.e., BRIGHT4 is in the most-significant-bit position of
the data byte) with the 3 remaining bits containing a
one, STATUS1 , and STATUS0 . This gives the same
result as using the read-word protocol with
0b10XXXXXX (0xAA and 0xA9) command. Use caution
with the shorter protocols in multimaster systems, since
a second master could overwrite the command byte
without informing the first master. During shutdown, the
serial interface remains fully functional.
