How to use ST NFC package to implement HW enhanced features

Read Example

//***********************************************************************/

//* the function send an ReadSingle command (0x0A 0x20) || (0x02 0x20)

//* example : StartAddress {0x00, 0x02} NbOfBlockToRead : {0x04}

//* the function will return 04 blocks read from address 0002

//* According to the ISO‐15693 maximum block read is 32 for the same sector
