7.2 GPIO interface
All GPIOs are capable of sinking and sourcing 4 mA of I/O current. GPIO [1] to GPIO [7] are
internally pulled down with 100 kΩ (nominal) resistors.
7.3 UART interface
The 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.
