GPIO [1] to GPIO [7] are internally pulled down with 100 kΩ (nominal) resistors.7.3 UART interfaceThe UART is compatible with the 16550 industry standard. Four signals are provided with the UART interface. The TXD and RXD pins are used for data while the CTS and RTS pins are used for flow control.Figure 6.
