Message Format for Writing the MAX7314

A write to the MAX7314 comprises the transmission of

the MAX7314’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 MAX7314

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 MAX7314 takes no further action

beyond storing the command byte.

last (A0) bits of the MAX7314 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 MAX7314 has four

possible slave addresses (Table 1), and therefore a

maximum of four MAX7314 devices can be controlled

independently from the same interface.

Table 1. MAX7314 Address Map

Any bytes received after the command byte are data

bytes. The first data byte goes into the internal register

of the MAX7314 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 MAX7314 internal registers because the

command byte address autoincrements (Table 2). A

diagram of a write to the output ports registers (blink

phase 0 registers or blink phase 1 registers) is given in

Figure 10.
