Hello,
Thank you for the answers. Sometimes it is difficult to get all restrictions
all together in one place from the ISO spec. :-(
Is there any restrictions for using p1 and p2 bytes in my own APDU commands
(with the unique CLA INS)?
For example:
Is the following APDU Command legal:
0xB0 0x20 0xFF 0x07 .....
Thank you.
Regards,
Jose

Subject: Re: [OCF] CLA, INS, SW available/reserved values
INS must not be an odd one (1 3 5 ...) due to ACK protocol at transport
level.
CLA Must no be any 6X or 9X, most of the time user app may use 00. ISO
standards indicates partitions in CLA, with reserved, forbidden and free
ranges.
SW1 must be one of 6X or 9X
Reading ISO 7816_3 and 7816_4 standards is strongly recommanded.
90 00 ;)
