GPIO Clear Falling Edge Interrupt Register (CLR_FAL_TRIGn)
Registers
The GPIO clear falling edge interrupt register (CLR_FAL_TRIGn) disables a falling edge on the GPIO pin
from generating a GPIO interrupt. The GPIO clear falling edge interrupt register (CLR_FAL_TRIG01) is
shown in
, CLR_FAL_TRIG23 is shown in
, CLR_FAL_TRIG4 is shown in
and described in
. See
to determine the CLR_FAL_TRIGn bit associated with each GPIO
bank and pin number.
