Lock All Blocks Command Reply:

The lock all blocks command sets the LKALL bit in System

EEPROM to mark as “read-only” the entire Measurement area of

the EEPROM. (The Application area is not locked by this bit.) No

access passwords need to be set prior to using this command.

The OPTION flag controls the response timing according to the

ISO 15693 standard, section 10.4.37.

Set Mode Command Reply:

The Set Mode command can change the mode of the chip

directly to ACTIVE mode (where logging events can take place)

or initially to a WAIT mode (where there is a programmed delay

before entering ACTIVE mode). This is the key command to start

logging.
