Universal Synchronous Asynchronous Receiver Transmitter (USART)
USART: RX impossible after any TX in ISO7816 mode T1
USART: Bad value in Number of Errors Register
Reception is impossible after any transmission in ISO7816 mode T1.
Configure USART in ISO7816 Mode T0 + INACK = 1 in US_MR during the reception. Once
reception is done, i.e. when the PDC Interruption ENDRX is received, reconfigure the USART in
Mode T1 in US_MR prior to transmitting.
The Number of Errors Register (US_NER) always returns 0 instead of the ISO7816 error
number.
None
