The function of each GPIO is controlled using the GPn_FN registers defined in Table 78. Note that
the selected function also depends on the associated GPn_DIR field described in Table 75.
See also Section 21.2 for additional details of each GPIO function, including the applicable de-
bounce times for GPIO input functions.
Table 78 GPIO Function Select Registers
Note that GPIO input functions 2h, 3h, 4h, 5h and 6h are edge-triggered only. The associated state
transition(s) are scheduled only when a rising or falling edge is detected on the respective GPIO pin.
At other times, it is possible that other state transition events may cause a state transition regardless
of the state of the GPIO input. See Section 11.3 for details of all the state transition events.
