HLTB Command [$50]
The HLTB command places a PICC in the Halt State, where it is not allowed to answer an REQB command. The
command and response are ISO/IEC 14443-3 compliant.
Sending the “Halt B” (HLTB) command (with a matching PUPI) after an ATQB response places the PICC in the Halt
State. A PICC in the Halt State will only respond to a WUPB command. PICCs in the Active State or already in the Halt
State are not permitted to answer this command.
PUPI:
CRC:
CRC:
If a HLTB command containing errors is received by the PICC, it is ignored and no response is sent.
The HLTB command is identical for 88SC and 88RF CryptoRF PICCs.
