To speed up the card detection time, we can enable the “Enforce ICC & PICC Exclusive Mode”

• Enforce ICC & PICC Exclusive Mode = {E0 00 00 2B 01 “New Mode Configuration”}.

<New Mode Configuration> #default value 01

00 = Both ICC & PICC interfaces can be activated at the same time.

01 = Either ICC or PICC interface can be activated at any one time. But not both!

• Read the existing status = {E0 00 00 2B 00}

Response {E1 00 00 00 01 “Current Mode”}

00 = Exclusive Mode is not activated. PICC Interface is available.

01 = Exclusive Mode is activated now. PICC Interface is not available until the ICC interface is

deactivated.

Hints：

1．Don’t insert any card into the contact card acceptor while the PICC is activate,or the PICC may

be deselected.

12. Request Command Test

This command is used for sending REQA/REQB by the reader to test antenna field and the

response.

• Command = {E0 00 00 26 02 “Command” “Speed”}

• Response = {E1 00 00 00 “Length” “Data”}

Command coding:

REQA = 01

REQB = 02

WUPA = 03

WUPB = 04

Speed coding:

106k bps = 00

212k bps = 01

424k bps = 02

Length:

No response: 00

ATQA: 02

ATQB: 0C

Others: RFU

Data:

Response Data (ATQA/ATQB/Others)

Hints:

1. Make sure the Auto PICC Polling is disabled first before sending this command.
