nRF51822 software interrupt (SWI)

Hello, guys!

We are using nRF51822 SoC with nRF5 SDK v12.3.0 and s130 SoftDevice. One of our desires is to use Software Interrupt (SWI) driver.

However, when I try to initialize SWI library with:

/* Initialize the library. */
err_code = nrf_drv_swi_init();
APP_ERROR_CHECK(err_code)

I get the following error:

../../../../../../components/drivers_nrf/hal/nrf_egu.h:69:39: error: unknown type name 'NRF_EGU_Type'

By taking a closer look at NRF_EGU_Type, I'm realizing that this type is defined only in the following header files:

There is no definition of NRF_EGU_Type in header files related to nRF51 SoCs.

What I am missing here and what would be the way of using SWI with nRF51 SoCs?

Thanks in advance for your time and efforts.

Sincerely,

Bojan.
