3.2.4 How to assign and read a GPIO
Some of the pins of the L6460 are indicated as GPIO (general purpose I/O). These pins can
be configured to be used in different ways depending on customer application. All GPIOs
can be used as digital input/output pins with digital value settable/readable using serial
interface or as analog input pins that can be converted using the A2D system. Some of the
pins can be used for special purposes: i.e. two of them can be used to access the pass
switch function, the other two are used as feedback pins for the auxiliary synchronous
switching regulators.
In the first software window click the L6460 device and then the "GPIOs" button, the
following window appears (Figure 25).
