Mode
Function
Normal Operation
Active
In Active mode, all functions of the module are available
and all processors are active. Radio transmission and
reception can be performed. Transitions to Standby mode
and Deep-sleep mode can only be initiated in Active mode.
Standby
In Standby mode, all processors are inactive, but all
peripherals can be active. The system clock is active and
power consumption is reduced via clock gating and power
gating. Standby mode is entered when all processors are
executing a wait-for-interrupt (WFI) instruction.
Deep-sleep
In Deep-sleep, only the 32kHz RTC is working, which
means the module can be moved to active state by an
RTC interrupt or by an external event through the
peripherals that are using the RTC. This mode is entered
by all processors setting the “sleep-deep” bit and then
executing a WFI instruction.
