• When an ACK signal LOW is detected after D0 and a stop condition is not sent from the master (µ-COM), the next
word address data can be read. [All words can be read]
• This command is ended by inputting a HIGH signal to the ACK signal after D0 and raising the SDA signal (stop
condition) using the SCL signal HIGH.
• Sequential reading can also be done with a random read.
