• Current Address Read
When the previous write or read operation finishes successfully up to the stop command and if the last accessed
address is taken to be “n”, then the address at “n+1” is read by sending the following command unless turning
the power off. If the end of the address range is reached internally, the address counter will roll over to 0000
The current address is undefined immediately after the power is turned on.
• Random Read
The one byte of data at the address as saved in the buffer can be read out synchronously to SCL by specifying
the address in the same way as for a write, and then issuing another start condition and sending the Control
Byte (R/W) = 1.
The final NACK is issued by the receiver that receives the data. In this case, this bit is issued by the master side.
