GPIOD Interrupt Priority Level (GPIOD IPL)—Bits 15–14
5.6.2.1
This field is used to set the interrupt priority level for the GPIOD IRQ. This IRQ is limited to priorities 0
through 2. It is disabled by default.
•

•
00 = IRQ disabled (default)
01 = IRQ is priority level 0
10 = IRQ is priority level 1
11 = IRQ is priority level 2
