Say yes here to select AT91 PIO GPIO driver. AT91 PIO
|
||||||
|
controller manages up to 32 fully programmable input/output
|
||||||
|
lines. Each I/O line may be dedicated as a general-purpose
|
||||||
|
I/O or be assigned to a function of an embedded peripheral.
|
||||||
|
The assignment to a function of an embedded peripheral is
|
||||||
|
the responsibility of AT91 Pinctrl driver. This driver is
|
||||||
|
responsible for the general-purpose I/O.
