Figure 10. Read, Write, and Interrupt Timing Diagrams  
Message Format for Reading  
The MAX7316 is read using the MAX7316’s internally  
stored command byte as an address pointer the same  
way the stored command byte is used as an address  
pointer for a write. The pointer autoincrements after  
each data byte is read using the same rules as for a  
write (Table 2). Thus, a read is initiated by first configur-  
ing the MAX7316’s command byte by performing a  
write (Figure 7). The master can now read n consecu-  
tive bytes from the MAX7316 with the first data byte  
being read from the register addressed by the initial-  
ized command byte. When performing read-after-write  
verification, remember to reset the command byte’s  
address because the stored command byte address  
has been autoincremented after the write (Table 2). A  
diagram of a read from the input ports register is shown  
in Figure 10 reflecting the states of the ports.  
Operation with Multiple Masters  
If the MAX7316 is operated on a 2-wire interface with  
multiple masters, a master reading the MAX7316 should  
use a repeated start between the write, which sets the  
MAX7316’s address pointer, and the read(s) that takes  
the data from the location(s) (Table 2). This is because it  
is possible for master 2 to take over the bus after master  
1 has set up the MAX7316’s address pointer but before  
master 1 has read the data. If master 2 subsequently  
changes the MAX7316’s address pointer, then master  
1’s delayed read can be from an unexpected location.  
Command Address Autoincrementing  
The command address stored in the MAX7316 circu-  
lates around grouped register functions after each data  
byte is written or read (Table 2).
