Full I
essary segment transitions are shown in Figure 7. ACK or NACK generation of an I
determined with the register bit
Generation of a 7-bit address is accomplished with one transmit segment. The upper 7 bits of the transmitted
character contain the 7-bit address. The remaining lower bit contains the command type (“read” or “write”).
