10.3.2 Interrupt
Control Register 1 (ICR1)
ICR1 is a 32-bit readable/writable register that specifies the individual input signal detection
modes of external interrupt input pins IRQ/
IRL7
to IRQ/
IRL0.
These settings are only valid for
pins configured as individual IRQ interrupts; that is, for pins for which the IRLM0 or IRLM1 bit
in ICR0 is set to 1.

IRQn Sense Select (n = 0 to 7)
Selects whether the corresponding individual pin
interrupt signal on the IRQ/IRL7 to IRQ/IRL0 pins is
detected on rising or falling edges, or at the high or
low level.
00: The interrupt request is detected on falling edges
of the IRQn input.
01: The interrupt request is detected on rising edges
of the IRQn input.
10: The interrupt request is detected when the IRQn
input is at the low level.
11: The interrupt request is detected when the IRQn
input is at the low level.
Note: When either level is selected, the IRQ level
interrupt request is not detected unless the
same level is sampled in three consecutive bus-
clock cycles.

These bits are always read as 0. The write value
should always be 0.
