1. Using the LLWU module, the external pins available for this chip do not require the associated peripheral function to be
enabled. It only requires the function controlling the pin (GPIO or peripheral) to be configured as an input to allow a
transition to occur to the LLWU.
2. Since LPO clock source is disabled, filters will be bypassed during VLLS0
3. The SMC_STOPCTRL[PORPO] bit in the SMC module controls this option.
