* <h1> General description </h1>
|
|
* <p>
|
|
* The APB GPIO is a configurable module allowing the use of 14 I/O lines.
|
|
* Each line can be configured independently.
|
|
* The GPIO module supports a wide variety of features concerning interrupts,
|
|
* which can be triggered by a low level, high level, positive or negative edge,
|
|
* or both edges.
|
