MEMORY FUNCTION COMMANDS
The “Memory Function Flow Chart” (Figure 5) describes the protocols necessary for accessing the
various data fields within the DS1986. The Memory Function Control section, 8-bit scratchpad, and the
Program Voltage Detect circuit combine to interpret the commands issued by the bus master and create
the correct control signals within the device. A three-byte protocol is issued by the bus master. It is
comprised of a command byte to determine the type of operation and two address bytes to determine the
specific starting byte location within a data field. The command byte indicates if the device is to be read
or written. Writing data involves not only issuing the correct command sequence but also providing a 12-
