AS39513 − Detailed Description
EEFULL – The EEPROM is full.
0 = More measurements can be logged.
1 = At least one measurement was not logged due to a lack of
EEPROM space.
ACTIVE – Controller state.
0 = Controller is in the IDLE or WAIT modes.
1 = Controller is in the ACTIVE mode.
Security Levels
The security level has mainly to do with what area of memory
is being accessed rather than which command is accessing it. 
See section Memory Access Levels.  A couple of columns from
the table can be eliminated with the following statements:
• All RFID commands can be used in the IDLE, WAIT, and
ACTIVE states, but not during LOGGING or initialization.
• The only command that changes the log controller state
is “Set Mode”.
• The ISO15693 state (Ready, Quiet, Selected) is
independent of the log controller state (IDLE, WAIT, etc.)
