nRF51822 Sleep modes

Hi All,

My question is about available sleep modes in nRF51822.

As I can find in nRF51 Series Reference Manual, and Product Specification documents, nRF51822 chip has two essential sleep modes, System-ON and System-OFF. Where the System-OFF is the deepest power saving mode, and in System-ON the system is either active or in sub-power sleep mode (Default selected sub-power mode is the Low Power mode).

I am using nrf51822, with active System-OFF (entered by calling sd_power_system_off function when needed), and active System-ON (entered when sd_app_evt_wait function is called), I'm using default System-ON mode(with Low Power sub-power sleep mode) which I think is the most saving mode during System-ON.

Please, I would like to be sure that I'm not missing any other power saving configuration or other nrf51 sleep modes ?

Many thanks in advance.

Ayman.
