/**
 * @defgroup nrfx_gppi Generic PPI layer
 * @{
 * @ingroup nrfx
 * @ingroup nrf_dppi
 * @ingroup nrf_ppi
 *
 * @brief Helper layer that provides the common functionality of PPI and DPPI drivers.
 *
 * Use PPI and DPPI drivers directly.
 * This layer is provided only to help create generic code that can be built
 * for SoCs equipped with either of these peripherals. When using this layer,
 * take into account that there are significant differences between the PPI and DPPI
 * interfaces that affect the behavior of this layer.
 *
 * One difference is that PPI allows associating of one task or event with
 * more than one channel, whereas DPPI does not allow this. In DPPI, the second
 * association overwrites the first one. Consequently, this helper layer cannot
 * be used in applications that need to connect a task or event to multiple
 * channels.
 *
 * Another difference is that in DPPI one channel can be associated with
 * multiple tasks and multiple events, while in PPI this is not possible (with
 * the exception of the association of a second task as a fork). Because of
 * this difference, it is important to clear the previous endpoints of the channel that
 * is to be reused with some different ones. Otherwise, the behavior of this
 * helper layer will be different, depending on the actual interface used:
 * in DPPI the channel configuration will be extended with the new endpoints, and
 * in PPI the new endpoints will replace the previous ones.
