3.6.3 External Interrupt Mode register (EXTMODE - 0x400F C148)
Table 10.
[1]
The bits in this register select whether each EINT pin is level- or edge-sensitive. Only pins
that are selected for the EINT function (see
NVIC register) can cause interrupts from the External Interrupt function (though of course
pins selected for other functions may cause interrupts from those functions).
Note: Software should only change a bit in this register when its interrupt is
disabled in the NVIC (state readable in the ISERn/ICERn registers), and should write
the corresponding 1 to EXTINT before enabling (initializing) or re-enabling the
interrupt. An extraneous interrupt(s) could be set by changing the mode and not
having the EXTINT cleared.

External Interrupt Flag register (EXTINT - address 0x400F C140) bit description
e.g. if the EINTx is selected to be low level sensitive and low level is present on
In level-sensitive mode, this bit is set if the EINT0 function is selected for
its pin, and the pin is in its active state. In edge-sensitive mode, this bit is
set if the EINT0 function is selected for its pin, and the selected edge
occurs on the pin.
This bit is cleared by writing a one to it, except in level sensitive mode
when the pin is in its active state.
In level-sensitive mode, this bit is set if the EINT1 function is selected for
its pin, and the pin is in its active state. In edge-sensitive mode, this bit is
set if the EINT1 function is selected for its pin, and the selected edge
occurs on the pin.
This bit is cleared by writing a one to it, except in level sensitive mode
when the pin is in its active state.
In level-sensitive mode, this bit is set if the EINT2 function is selected for
its pin, and the pin is in its active state. In edge-sensitive mode, this bit is
set if the EINT2 function is selected for its pin, and the selected edge
occurs on the pin.
This bit is cleared by writing a one to it, except in level sensitive mode
when the pin is in its active state.
In level-sensitive mode, this bit is set if the EINT3 function is selected for
its pin, and the pin is in its active state. In edge-sensitive mode, this bit is
set if the EINT3 function is selected for its pin, and the selected edge
occurs on the pin.
This bit is cleared by writing a one to it, except in level sensitive mode
when the pin is in its active state.
Reserved, user software should not write ones to reserved bits. The value
read from a reserved bit is not defined.
