same rules as for a write. Thus, a read is initiated by first
configuring the MAX7306/MAX7307’s command byte
by performing a write (Figure 13). The master can now
read n consecutive bytes from the MAX7306/
MAX7307 with the first data byte being read from the
register addressed by the initialized command byte
(Figure 15). When performing read-after-write verifica-
tion, remember to reset the command byte’s address
because the stored command byte address has been
autoincremented after the write (see Table 1).
Operation with Multiple Masters
If the MAX7306/MAX7307 are operated on a 2-wire
interface with multiple masters, a master reading the
MAX7306/MAX7307 should use a repeated start
between the write that sets the MAX7306/MAX7307’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 MAX7306/MAX7307’s address pointer, but before
master 1 has read the data. If master 2 subsequently
changes the MAX7306/MAX7307 ’s address pointer,
then master 1’s delayed read can be from an unexpect-
ed location.
Bus Timeout
Clear device configuration register 0x27 bit D7 to
enable the bus timeout function (see Table 2), or set it
to disable the bus timeout function. Enabling the time-
out feature resets the MAX7306/MAX7307 serial-bus
interface when SCL stops either high or low during a
read or write. If either SCL or SDA is low for more than
