In the SPIS peripheral example project CONSTLAT mode is set with the following function. You can check out the project to see how it's implemented.

NRF_POWER->TASKS_CONSTLAT = 1;

Best regards,

Simon

Hi Simonr

Thank you so much for the reply, But if we want to use Constant latency in System on mode how to use it?

It's not necessary to use sd_power_mode_set() to go into low power mode, as this is done by default when the CPI is asleep. I would recommend using the sd_app_evt_wait(); function to go to sleep instead, as it is easier and a smoother way of doing so. This is already discussed in this ticket, so please check it out for more details.

Best regards,

Simon
