Message Format for Writing the MAX7316  
A write to the MAX7316 comprises the transmission of  
the MAX7316s slave address with the R/W bit set to  
zero, followed by at least 1 byte of information. The first  
byte of information is the command byte. The com-  
mand byte determines which register of the MAX7316  
is to be written to by the next byte, if received (Table 2).  
If a STOP condition is detected after the command byte  
is received, then the MAX7316 takes no further action  
beyond storing the command byte.  
last (A0) bits of the MAX7316 slave address are always  
1, 0, 0, 0, and 0. Slave address bits A6 and A2 are  
selected by the address input AD0. AD0 can be con-  
nected to GND, V+, SDA, or SCL. The MAX7316 has four  
possible slave addresses (Table 1), and therefore a  
maximum of four MAX7316 devices can be controlled  
independently from the same interface.

Table 1. MAX7316 I C Slave Address Map  
Any bytes received after the command byte are data  
bytes. The first data byte goes into the internal register  
of the MAX7316 selected by the command byte (Figure  
8). If multiple data bytes are transmitted before a STOP  
condition is detected, these bytes are generally stored  
in subsequent MAX7316 internal registers because the  
command byte address autoincrements (Table 2). A  
diagram of a write to the output ports registers (blink  
phase 0 register or blink phase 1 register) is given in  
Figure 10.
