WARNING:
GPIO_09 and WCI_RX are used as special HW flags during boot.
If they are used as GPIOs, they must be connected via a 3-state buffer to
avoid any undesirable effect during the boot.
NOTE:
When the UART signals are used as the communication port between the
host and the modem, the RTS must be connected to GND (on the module
side) if flow control is not used.
If the UART port is not used, all UART signals can be left disconnected.
NOTE:
Unless otherwise specified, RESERVED pins must be left unconnected
(floating).
