In the chapter of I/O Pin Selection, how to select pins used as external interrupts is explained. I/O pins used as
interrupts are classified into two groups: SYS group and APP group. You can select six pins each from both SYS
group and APP group. Table General Purpose Input/Output (GPIO)-23 shows I/O pins belonging to SYS group,
and Table General Purpose Input/Output (GPIO)-25 shows I/O pins belonging to APP group. Figure General
