11.1.3 Modes of operation
11.1.3.1 Run mode
In Run mode, the PORT operates normally.
11.1.3.2 Wait mode
In Wait mode, PORT continues to operate normally and may be configured to exit the
Low-Power mode if an enabled interrupt is detected. DMA requests are still generated
during the Wait mode, but do not cause an exit from the Low-Power mode.
11.1.3.3 Stop mode
In Stop mode, the PORT can be configured to exit the Low-Power mode via an
asynchronous wakeup signal if an enabled interrupt is detected.
11.1.3.4 Debug mode
In Debug mode, PORT operates normally.
