DESCRIPTION
Writes 64-bit challenge for SHA-1 processing. Required
immediately prior to all Compute MAC and Compute Next Secret
commands.
Computes hash operation of message block with logical 1s in
place of the ROM ID.
Computes hash operation of message block using the ROM ID.
Clears the 64-bit secret to 0000 0000 0000 0000h.
Generates new global secret.
Generates new unique secret.
Sets lock bit to prevent changes to the secret.
Reads data from memory starting at address XX.
Writes data to memory starting at address XX.
Copies shadow RAM data to EEPROM block containing address
XX.
Recalls EEPROM block containing address XX to RAM.
Permanently locks the block of EEPROM
containing address XX.
Sets 1-Wire interface timings to overdrive.
Sets 1-Wire interface timings to standard (factory default).
Resets DS2784 (software POR).
