• INACK: Inhibit Non Acknowledge
0 = The NACK is generated.
1 = The NACK is not generated.
• DSNACK: Disable Successive NACK
0 = NACK is sent on the ISO line as soon as a parity error occurs in the received character (unless INACK is set).
1 = Successive parity errors are counted up to the value specified in the MAX_ITERATION field. These parity errors gener-
ate a NACK on the ISO line. As soon as this value is reached, no additional NACK is sent on the ISO line. The flag
ITERATION is asserted.
• MAX_ITERATION
Defines the maximum number of iterations in mode ISO7816, protocol T = 0.
• FILTER: Infrared Receive Line Filter
0 = The USART does not filter the receive line.
