MEMORY FUNCTION FLOW CHART Figure 6 (cont’d)
READ APPLICATION REGISTER [C3h]
This command is used to read the application register or the register scratchpad. As long as the
application register is not yet locked, one will receive data from the register scratchpad. After the
application register is locked the DS2430A will transmit data from the application register, making the
register scratchpad inaccessible for reading. The contents of the status register indicates where the data
received with this command came from. After issuing the Read Application Register command, the
master must provide the 1-byte starting address from where data is to be read. The DS2430A will
automatically increment the address after every byte read by the master. After the data of address 07h has
been read, the address counter will wrap around to 00h for the next byte and reading continues until the
master sends a reset pulse.
COPY & LOCK APPLICATION REGISTER [5Ah]
After the data stored in the register scratchpad has been verified the master may send the Copy & Lock
Application Register command followed by a validation key of A5h to transfer the contents of the entire
register scratchpad to the application register and to simultaneously write-protect it. The master may
cancel this command by sending a reset pulse instead of the validation key. After the validation key was
transmitted, the application register will contain the data of the register scratchpad. Further write accesses
to the application register will be denied. The Copy & Lock Application Register command can only
be executed once.
