A_FLAG:
Indicates whether the reader tries to read a ISO18000-3M3 tag in Secured State.
If A_FLAG is set the protocol contains the access password.
A_FLAG:
b0
no access password in protocol
b1
access password and access password length in protocol. Reader exe-
cute access command
A_PW_LNG:
Length of Access Password.
A_PW:
Access password which is used to access to the secured state of the Tag.
DB-ADR:
First block number to be read. Depending on EXT_ADR. First block can be any value be-
tween 0 and 255 or 0 and 65535.
DB-N:
Number of data blocks to be read from the Transponder, starting at DB-ADR.
The maximum number of DB-N, depends on DB-Size and the interface transmit buffer
size TX-BUF. The maximum number of DB-N is:
(TX-BUF - 10 )/(DB-Size+1) e.g. Block size 4 (DB-N = (512
– 10) / (4+1) = 100).
DB-SIZE:
Number of bytes of one data block. This value depends on the specification of the Tran-
sponder
SEC-STATUS:
(only ISO15693 Transponder)
Block security status of followed data block. If supported by the ISO15693 transponder.
DB:
Requested data block. The block size is defined by DB-SIZE.
TAG ERROR:
TAG ERROR code of Transponder response. This byte is only available if STATUS =
0x95. See:
ANNEX F: Transponder Error Codes
Notes:
Only one Transponder can be read in the non-addressed mode.
ISO15693:
- A read from 1 block uses a Read Single Block command to the ISO15693 Transponder.
- If a ISO15693 Transponder does not support Read Multiple Blocks commands several
Read Single Block commands are used for this Transponder.
