or 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.
