Reference Manual for uTrust 4701F and uTrust 4711F Readers
6.3.4.4. READER_CNTLESS_SET_TYPE
This escape command configures the type of cards the reader will poll for.
Using this command can improve the polling efficiency for applications where only specific types of
cards are expected.
This escape command needs to be used with care.
For example, we should not disable the polling for a given type of the card, after having placed that
card on the reader.
Since reader would immediately stop polling for the card, it would never detect that card is removed.
The input buffer shall contain two or three bytes
Byte0
Byte1
Byte3
