Ensure that you don't have any peripheral enabled like enabled RX in UART, TIMER enabled, GPIOTE task/event enabled etc. any peripheral that requires HF clock will prevent system from shutting it down.

Yes,i enabled UART for DTM,enabled PWM(used timer 2).i initialize these peripheral and then sleep. need to disable them before sleep?Thanks a lot !
