General-Purpose Interface Functional Description

25.4 General-Purpose Interface Functional Description
shows the general-purpose interface description.
Figure 25-5. General-Purpose Interface Description
details GPIOs in the general-purpose interface block diagram with their configuration registers
and their main functional paths:
•
The synchronous path (for active mode operation) used to generate a synchronous interrupt request
on expected event detection on any input GPIO; the synchronous interrupt request lines 1 and 2 are
active based on their respective interrupt-enable 1 and 2 registers (GPIOi.
and
GPIOi.
). See
.
Figure 25-6. Synchronous Path
•
The asynchronous path (for idle mode operation) used to generate an asynchronous wake-up request
on the expected edge detection on any input GPIO; the asynchronous wake-up request line is active
based on the wakeup-enable register. See
.
