THE SETTING OF THIS BIT IS OTP !
0: PAGE 3 read/write
1: PAGE 3 read only; Configuration Byte and Password TAG fixed
THE SETTING OF THIS BIT IS OTP !
0: PAGE 1 and 2 read/write
1: PAGE 1 no read/no write
PAGE 2 read only (when transponder is in password mode)
PAGE 2 no read/no write (when transponder is in crypto mode)
Configuration Byte / Bit 6:
Bit 6 = ‘0’: Page 3 is read/write.
Bit 6 = ‘1’: Page 3 can only be read. This process is irreversible !
ATTENTION: Do not set Bit 6 of the Configuration Byte to ‘1’ before having written the
final data into Page 3 (including the Configuration Byte and Password TAG) of the
transponder.
Configuration Byte / Bit 7:
Bit 7 = ‘0’: Pages 1 and 2 are read/write.
Bit 7 = ‘1’: Pages 1 and 2 are locked against writing. This process is irreversible !
ATTENTION: Do not set Bit 7 of the Configuration Byte to ‘1’ before having written the
final data into Pages 1 and 2 of the transponder.
