32 a number of GPIOs. Thus, each GPIO is named according to an alphabetical port
33 name and an integer GPIO name within the port. For example, GPIO_PA0, GPIO_PN6,
37 implemented GPIOs within each port varies. GPIO registers within a controller

12 CD-ROM, LS-120 and tape drives use the parallel port to connect to their
