IMXRT UARTS Hardware RS485 and Smartcard operation

I am trying to configure the RT10XX families to run RS485 with Hardware flow control and Smartcard operation.

Is this possible with these parts, an initial reading of the datasheet seems to suggest not.

Thanks Igor for the prompt reply, that answers the first part of the question, I checked this section of the document but I can't find support for ISO7816 smartcards using a UART, is there an app note to point me in the right direction for Smart card support?

Many thanks

George

Hi George

for rs485 usage one can look at sect.39.2.2.4 Transceiver driver enable

using RTS_B i.MX RT1050 Reference Manual
https://www.nxp.com/docs/en/reference-manual/IMXRT1050RM.pdf

Best regards
