@brief       Support for the STM32G0316-DISCO board.

### General information

The ST [STM32G0316-DISCO](https://www.st.com/en/evaluation-tools/stm32g0316-disco.html)
is an evaluation board supporting a ARM Cortex-M0 STM32G031J6 microcontroller
with 8KB of RAM and 32KB of ROM Flash.

### Pinout

In an SO8 package, this MCU uses multi-bonding to run multiple ports to the same pins.
See [this application note as reference](https://www.st.com/resource/en/application_note/dm00443870-getting-started-with-stm32g0-series-hardware-development-stmicroelectronics.pdf).
This means the responsibility is on the firmware configurer to take special care when configured IO, ensuring that
ports are not conflicting on each pin.

### Flash the board

The STM32G0316-DISCO board includes an on-board ST-LINK programmer and can be
flashed using OpenOCD.

To flash this board, just use the following command:
```
 make BOARD=stm32g0316-disco flash -C examples/basic/hello-world
 ```
### UART Terminal Interaction

Due to the limited number of pins, to get stdio UART traffic, use a USB->UART adapter
like the CP2104 from Adafruit (http://adafru.it/954). Connect the adapter's TX line
to the MCU RX pin (PB6, Pin 8) and the adapter's RX line to the MCU's TX pin -
(PB7, pin 1).
