Query regarding TASKS_CONSTLAT

[skulkarni]

We are migrating BLE application code from SDK-12.3 to SDK-15.3. 

Our firmware uses SPIS module. Now in the example code I could see 

NRF_POWER->TASKS_CONSTLAT = 1;

What is the use of making this bit high.

Without setting this bit my application works.

Thanks in advance

Setting Constlat = 1 will force the HF clock to be always on. See the product specification
