UART

The QSCOM standard defines three independent UART Ports (UARTA – UARTC). UARTA is used to output serial debugging information. UARTC supports hardware RTS/CTS handshake.

Pin Signal Description type I/O
89 UARTA_TXD Transmit Data output signal 3V3 O
90 UARTA_RXD Receive Data input signal 3V3 I
91 UARTB_TXD Transmit Data output signal 3V3 O
92 UARTB_RXD Receive Data input signal 3V3 I
93 UARTC_TXD Transmit Data output signal 3V3 O
94 UARTC_RXD Receive Data input signal 3V3 I
95 UARTC_CTS Clear to Send input signal 3V3 I
96 UARTC_RTS Request to Send output signal 3V3 O

Note

Keep attention to the unusual DCE naming convention NXP is using for CTS(output)/RTS(input).
