Non-volatile memory Configuration Contactless CCID Protocols
September 20, 2024 at 2:48 AMNFC / RFID HF protocols enabled in PC/SC mode
Address : 0231
(bank 2, register 31
)
Size : 2 bytes
Type : WORD
Default : 14E7
Description
Select the 13.56MHz protocols that the product is looking for.
Remark
-
Disabling the unwanted protocols speeds up the card detection (polling loop) and decreases the average power consumption.
-
Default value is NFC A+B+F+V (ISO/IEC 14443 A+B, X6319-4, ISO/IEC 15693) plus Innovatron, Inside Pico, ST SR, ACK CTS. Don’t forget to activate the protocol(s) you want.
-
This register is not used in Smart Reader mode (the list of Protocols is constructed according to the Templates).
