The second (A5), third (A4), fourth (A3), sixth (A1), and
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.
Message Format for Writing the MAX7316
A write to the MAX7316 comprises the transmission of
the MAX7316’s 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.
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.
