written. Writing data involves not only issuing the correct command sequence by also providing a 12-volt
programming voltage at the appropriate times. To execute a write sequence, a byte of data is first loaded
into the scratchpad and then programmed into the selected address. Write sequences always occur a byte
at a time. To execute a read sequence, the starting address is issued by the bus master and data is read
from the part beginning at that initial location and continuing to the end of the selected data field or until
a reset sequence is issued. All bits transferred to the DS2502 and received back by the bus master are sent
least significant bit first.
