XBEE1 bus
XBEE1 is enabled by default. The enable pin is 'XBEE1_EN_PIN'. To disable this bus call 'XBEE1_DISABLE', to re-enable it call 'XBEE1_ENABLE'.

#define	XBEE1_CS_PIN GPIO_PIN(PA, 18)

#define	XBEE1_INT_PIN GPIO_PIN(PA, 21)

XBEE2 bus
XBEE2 is enabled by default. The enable pin is 'XBEE2_EN_PIN'. To disable this bus call 'XBEE2_DISABLE', to re-enable it call 'XBEE2_ENABLE'.
#define	XBEE2_EN_PORT PORT->Group[PB]

#define	XBEE2_EN_MASK (1 << 10)

#define	XBEE2_EN_PIN GPIO_PIN(PB, 10)

#define	XBEE2_CS_PIN GPIO_PIN(PA, 14)

#define	XBEE2_INT_PIN GPIO_PIN(PA, 15)

I2C bus
I2C is enabled by default. The enable pin is 'I2C_EN_PIN'. To disable this bus call 'I2C_DISABLE', to re-enable it call 'I2C_ENABLE'.
#define	I2C_EN_PORT PORT->Group[PB]

#define	I2C_EN_MASK (1 << 11)

#define	I2C_EN_PIN GPIO_PIN(PB, 11)

#define	I2C_DISABLE (I2C_EN_PORT.OUTCLR.reg = I2C_EN_MASK)

SX127X
SX127X configuration (on XBEE1 port). This particular board has merged DIO0 and DIO1 interrupt pins into one. The driver will always check the interrupt type in the ISR handler, so it's enough to set the DIO0 pin in order to handle both DIO0 and DIO1.
