Table 4. Autoincrement Rules
COMMAND BYTE ADDRESS RANGE
x0000000 to x1111110
x1111111
AUTOINCREMENT BEHAVIOR
Command address autoincrements after byte read or written
Command address remains at x1111111 after byte written or read
ing a write (Figure 8). The master can now read n con-
secutive bytes from the MAX6956, with the first data
byte being read from the register addressed by the ini-
tialized command byte. When performing read-after-
write verification, remember to reset the command
byte ’s address because the stored control byte
address generally has been autoincremented after the
write (Table 4). Table 5 is the register address map.
Operation with Multiple Masters
If the MAX6956 is operated on a 2-wire interface with
multiple masters, a master reading the MAX6956
should use a repeated start between the write, which
sets the MAX6956’s address pointer, and the read(s)
that takes the data from the location(s). This is because
it is possible for master 2 to take over the bus after
master 1 has set up the MAX6956’s address pointer but
before master 1 has read the data. If master 2 subse-
