* This is a GPIO interrupt dispatcher module. It consists of gpiointerrupt.c
* and gpiointerrupt.h. EFM32 has two GPIO interrupts (Odd and Even). If more
* than two interrupts are used then interrupt routine must dispatch. This
* driver provides small dispatcher for both GPIO interrupts enabling
* handling of up to 16 GPIO pin interrupts.
*
* It is up to the user to set up and enable interrupt on given pin. Dispatcher
* handles cleaning of interrupt flags.
*
* In order to use GPIO Interrupt Dispatcher it has to be initialized first by
* calling GPIOINT_Init(). Then each pin must be configured by first registering
* the callback for given pin (GPIOINT_CallbackRegister()) and then setting up
* and enabling the interrupt in GPIO module.

* @details
* This is a software manager module for non-volatile memory. It consists of
* nvm.c, nvm.h and nvm_hal.h. In addition to this it requires a valid nvm_hal.c.
* This lets the manager work with different types of memory.
* Files nvm_config_template.* shows possible configuration of objects and could
* be used as template for customer application.
*
* The module has the following public interfaces:
*
* NVM_Init()
* NVM_Erase()
* NVM_Write()
* NVM_Read()
* NVM_WearLevel()
*
* Users have to be aware of the following limitations of the module:
* - Maximum 254 objects in a page and 256 pages (limited by uint8_t).
