enum iso7816_inhibit_nack iso7816_config_t::inhibit_nack

Inhibit Non Acknowledge:

• 0: the NACK is generated;
• 1: the NACK is not generated.

enum iso7816_protocol_type iso7816_config_t::protocol_t

ISO7816 protocol type.

enum iso7816_successive_recv_nack iso7816_config_t::successive_recv_nack

Disable successive NACKs.

• 0: NACK is sent on the ISO line as soon as a parity error occurs in the received character. Successive parity errors are counted up to the value in the max_iterations field. These parity errors generate a NACK on the ISO line. As soon as this value is reached, no additional NACK is sent on the ISO line. The ITERATION flag is asserted.
