I wander if the LLWUP unit has to be gated to work. I do not find a bit field to do so. Confirm it does not need.
For activating the interrupt of the LLWUP unit from external pin, It is necessary to:
1) enable the interrupt of the pins itself: -> PORT_HAL_SetPinIntMode(BOARD_SW_LLWU_BASE, BOARD_SW_LLWU_PIN, kPortIntFallingEdge);
2) enable the interrupt of the pin in the LLWUP unit -> LLWU_HAL_SetExternalInputPinMode(LLWU_BASE,kLlwuExternalPinDisabled, (llwu_wakeup_pin_t)BOARD_SW_LLWU_EXT_PIN);
Are all the previous actions necessary and sufficient???
Will the interrupt of the pin change requested or simply ignored in such initialization???
