5.18.4 GPIO (23-16) Interrupt Enable Register (Offset 0x68B)
For each GPIO:
1 = Interrupt enabled
0 = Interrupt masked (default)
If any GPIO interrupt is configured as non-maskable (see the
Non-Maskable Register (Offset 0x692)
) and enabled, then no further changes to any
settings that affect that GPIO can be made (except for GPIO_TEST and GPIO_OUT).
5.18.5
GPIO (23-16) Interrupt Level/Edge Register (Offset 0x68C)
For each GPIO:
1 = Edge
0 = Level (default)
5.18.6 GPIO (23-16) Interrupt Polarity Register (Offset 0x68D)
For each GPIO, this register sets the interrupt detection sensitivity of each interrupt
pin (active high/low or rising/falling edge depending on the level/edge mode):
1 = Active high/rising edge
0 = Active low/falling edge (default)
5.18.7
GPIO (23-16) Interrupt Both Edges Register (Offset 0x68E)
For each GPIO:
1 = Both-edges mode enabled
0 = Both-edges mode disabled (default)
When enabled, Both-edges mode causes interrupts to be generated on both rising
and falling edges.
NOTE
The GPIO bit must be in Edge mode for Both-edges mode to work.
5.18.8
GPIO (23-16) Interrupt Status/Clear Register (Offset 0x68F)
For each GPIO:
1 = Interrupt pending
0 = No interrupt (default)
Write a ‘1’ to a bit to clear the interrupt pending status.
