41.4.2.4 Interrupt Request Enable Register (IRER)
This register is used to enable the interrupt messaging from the wakeup/interrupt pads to the interrupt
controller.
41.4.2.5 Wakeup Request Enable Register (WRER)
This register is used to enable the system wakeup messaging from the wakeup/interrupt pads to the mode
entry and power control modules.
41.4.2.6 Wakeup/Interrupt Rising-Edge Event Enable Register (WIREER)
This register is used to enable rising-edge triggered events on the corresponding wakeup/interrupt pads.
Note: The RC_API can only be configured on the rising edge.
