Hi Yesilkaya,
No, NXP does not guarantee CLRC663 will work fine if you try to send non-standard proprietary commands different from those listed below:
Read/write mode supporting ISO/IEC 14443A/MIFARE
• Read/write mode supporting ISO/IEC 14443B
• Read/write mode supporting JIS X 6319-4 (comparable with FeliCa1 (see
Section 21.5) scheme)
• Passive initiator mode according to ISO/IEC 18092
• Read/write mode supporting ISO/IEC 15693
• Read/write mode supporting ICODE EPC UID/ EPC OTP
• Read/write mode supporting ISO/IEC 18000-3 mode 3/ EPC Class-1 HF
Nevertheless, if you have a proprietary ISO14443-4 card for which you have a native set of APDU's, you have more freedom when using CLRC663 in T=CL protocol since reader will push through APDU in the payload (reader doesn't care what you are sending to your card). Then, it will be up to your card to reply with "ok" or with "error message". When using MIFARE Classic related commands (on ISO/IEC14443-3), then you have to stick to only available MIFARE available commands in the list.
I hope this helps you.
Cheers
Rodolfo
