Interrupt detection method
1 : Edge
0 : Level
Function
This register is used to set the detection method (trigger) for interrupts to GPIO pins. The INTT[15..0] bits
correspond to the GPIO[15..0] 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
GIUINTALSELL register (GPIO Interrupt Active Level Select Register) is detected.
Caution The function of GPIO[15] is fixed as DCD# signal input.
