Port x Alternate Register 0
The Port x Alternate register 0 is used to clear edge triggered interrupts. If an edge
triggered interrupt occurs, writing 1 to the corresponding bit of this register will clear it.
Port x Alternate Register 1
In conjunction with the other GPIO Control registers, the Port x Alternate Register 1 (see
Table
mode selection, see
Port x Alternate Register 2
In conjunction with the other GPIO Control registers, the Port x Alternate Register 2 (see
Table
mode selection, see
10) controls the operating modes of the GPIO port pins. For more details on GPIO
