DESCRIPTION
This command copies the shadow RAM to the target EEPROM block. Copy data

commands that target locked blocks are ignored. While the Copy Data command is
executing, the EEC bit in the EEPROM register is set to 1, and write data commands
with MAddr set to any address within the target block are ignored. Read data and
write data commands with MAddr set outside the target block are processed while
the copy is in progress. The Copy Data command execution time, t EEC , is 2ms
typical and starts after the FCmd byte is acknowledged. Subsequent copy or lock
commands must be delayed until the EEPROM programming cycle completes.

the EEPROM register must be set to 1 before the Lock command is executed. If the
LOCK bit is 0, the Lock command has no effect. The Lock command is permanent;
a locked block can never be written again. The Lock command execution time,
t EEC , is 2ms typical and starts after the FCmd byte is acknowledged. Subsequent
copy or lock commands must be delayed until the EEPROM programming cycle
completes.

This command initiates a read of the unique 64-bit ROM ID. After the Read ROM ID
command is sent, the ROM ID can be read with the following sequence:
S SAddr R Data0 A Data1 A ... Data7 N P.
