sd_app_evt_wait and unprivileged thread mode


Our board is based on nRF52832 with S132 5.1.0, without RTOS. Now we have a requirement to protect sensitive memory areas with MPU, so I'm trying to run firmware in unprivileged mode (CONTROL=0x01), and I got Bus Fault in sd_app_evt_wait() handler. Should I use __WFE() instead, is it safe with SoftDevice enabled?
