The first byte of information is the command byte, which deter- mines which register of the MAX6955 is to be written by the next byte, if received. If a STOP condition is detect- ed after the command byte is received, then the MAX6955 takes no further action (Figure 7) 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 MAX6955 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 MAX6955 internal registers because the command byte address generally autoincrements (Table 6) (Figure 9).
