to wake up the processor to a state where it can service the interrupt. Latency is increased in deep
‑
sleep
mode.
Note
The IoT System uses latches to implement the WIC, unlike in the standard Cortex-M33 processor.
FCLK
can be gated completely during WIC-based deep
‑
sleep. This complete gating is not a standard
Cortex-M33 processor feature.
