READ MEMORY [F0H]
The read memory command may be used to read the entire memory. After issuing the command, the
master must provide the 2-byte target address. After the two bytes, the master reads data beginning from
the target address and may continue until the end of memory, at which point logic 1’s will be read. It is
important to realize that the target address registers will contain the address provided. The ending
offset/data status byte is unaffected.
The hardware of the DS2433 provides a means to accomplish error-free writing to the memory section.
To safeguard reading data in the 1-Wire environment and to simultaneously speed up data transfers, it is
recommended to packetize data into data packets of the size of one memory page each. Such a packet
would typically store a 16-bit CRC with each page of data to insure rapid, error-free data transfers that
eliminate having to read a page multiple times to determine if the received data is correct or not. (See the
Book of DS19xx iButton Standards, Chapter 7 or Application Note 114 for the recommended file
structure.)
