Function
D[15..0]
INTT[31..16]
Interrupt detection method
1 : Edge
0 : Level
This register is used to set the detection method for interrupts to GPIO pins. The INTT[31..16] bits correspond to
the GPIO[31..16] pins.
When “1” is set to the corresponding INTT bit, the edge detection method is used for the interrupt signal at the
corresponding GPIO pin (an interrupt is triggered when the signal state changes from low to high or from high to
low).
The level detection method is used when “0” is set, in which case the level set to corresponding bit in the
GIUINTALSELH register (GPIO Interrupt Active Level Select Register) is detected.
