UART port mapping in DCE/DTE mode defines RTS_B and CTS_B in different manner as used in SMARC 2.0 spec. In
the following table the pin and signal direction are like in SMARC 2.0 spec.

Only usable if APPROTECT key does not use SPI (omit SPI level shifter TXB0104RUT) and stuffed additional

resistors
