/**

* @brief Function for acquiring shared peripheral resources associated with

* the specified peripheral.
|

*
|
||||
* Certain resources and registers are shared among peripherals that have
|
||||
* the same ID (for example: SPI0, SPIM0, SPIS0, TWI0, TWIM0, and TWIS0 in
|
||||
* nRF52832). Only one of them can be utilized at a given time. This function
|
||||
* reserves proper resources to be used by the specified peripheral.
|
||||
* If NRFX_PRS_ENABLED is set to a non-zero value, IRQ handlers for peripherals
|
||||
* that are sharing resources with others are implemented by the @ref nrfx_prs
|
||||
* module instead of individual drivers. The drivers must then specify their
|
||||
* interrupt handling routines and register them by using this function.
|
||||
*
|
||||
* @param[in] p_base_addr Requested peripheral base pointer.
|
||||
* @param[in] irq_handler Interrupt handler to register.
|
||||
*
|
||||
* @retval NRFX_SUCCESS If resources were acquired successfully or the
|
||||
* specified peripheral is not handled by the PRS
|
||||
* subsystem and there is no need to acquire resources
|
||||
* for it.
|
||||
* @retval NRFX_ERROR_BUSY If resources were already acquired.
