/**

* @ingroup boards
* @brief Support for the SenseBox MCU with SAMD21 board.
### General information
[SenseBox](https://www.sensebox.de/) is a do-it-yourself kit for stationary
and mobile sensor stations.
SenseBox board is based on the Atmel SAMD21G18A microcontroller. See
@ref cpu_samd21.
### Flash the board
1. Put the board in bootloader mode by double tapping the reset button.<br/>
When the board is in bootloader mode, the user led (red) oscillates smoothly.
2. Use `BOARD=sensebox` with the `make` command.<br/>
Example with `hello-world` application:
```
make BOARD=sensebox_samd21 -C examples/hello-world flash
```
### Accessing STDIO via UART
To access the STDIO of RIOT, a FTDI to USB converted needs to be plugged to
the UART/Serial 1 pins on the board.
### On I2C port
I2C port is enabled by default. To disable it use ```I2C_DISABLE```. To
re-enable use ```I2C_ENABLE```.
### On XBEE ports
XBEE1 and XBEE2 ports are enabled by default. To disable any of them use
```XBEEn_DISABLE```. To re-enable use ```XBEEn_ENABLE```.
On the board there is a reset circuit for this ports that delays the reset
signal from the enable signal for about 300ms. Because of that a delay has
been introduced in the ```board_init``` function, so that any SPI device
connected to the ports is reset before use.
#### SX127X radio
The pin configuration for the SX127X radio on the
*boards/sensebox/include/board.h** file assumes that it will be connected to
the XBEE1 port. If a different configuraion is needed please modify this
file.
#### SD card
The pin configuration for the mSD-Bee module radio on the
*boards/sensebox/include/sdcard_spi_params.h** file assumes that it will be
connected to the XBEE2 port. If a different configuraion is needed please
modify this file.

* - usage of the internal 8MHz oscillator directly, divided by N if needed
*
*
* The PLL option allows for the usage of a wider frequency range and a more
* stable clock with less jitter. This is why we use this option as default.
*
* The target frequency is computed from the PLL multiplier and the PLL divisor.
* Use the following formula to compute your values:
*
* CORECLOCK = ((PLL_MUL + 1) * 1MHz) / PLL_DIV
*
* NOTE: The PLL circuit does not run with less than 32MHz while the maximum PLL
* frequency is 96MHz. So PLL_MULL must be between 31 and 95!
*
*
* The internal Oscillator used directly can lead to a slightly better power
* efficiency to the cost of a less stable clock. Use this option when you know
* what you are doing! The actual core frequency is adjusted as follows:
*
* CORECLOCK = 8MHz / DIV
