GPIO Registers
25.4.1.12 GPIO_IRQWAKEN_0 Register (offset = 44h) [reset = 0h]
GPIO_IRQWAKEN_0 is shown in
and described in
.
Per-event wakeup enable vector (corresponding to first line of interrupt). Every 1-bit field in the
GPIO_IRQWAKEN_0 register enables a specific (synchronous) IRQ request source to generate an
asynchronous wakeup (on the appropriate swakeup line). This register allows the user to mask the
expected transition on input GPIO from generating a wakeup request. The GPIO_IRQWAKEN_0 is
programmed synchronously with the interface clock before any Idle mode request coming from the host
processor. Note: In Force-Idle mode, the module wake-up feature is totally inhibited. The wake-up
generation can also be gated at module level using the EnaWakeUp bit from GPIO_SYSCONFIG register.
