This Escape command is used to enable or disable the ATR validation by the firmware in 
ISO/IEC 7816 mode. 

In case the card would emit an ATR that is not ISO/IEC 7816 compliant, the card reader may 
fail to power up the card. In these cases, disabling ATR validation will let you work with the card 
regardless of ISO conformity of the ATR. 

By default, ATR validation is enabled.

 

The first byte of the input buffer will contain the Escape code; the next byte will contain the 
control byte.
