Note *: When the interrupt occurs in the same time, the priority is (1-1 > 1-2); (2-1> 2-2 > 2-3)
Note **: The interrupt types of these sources are programmable in slave mode.

pending. If the interrupt is granted, the interrupt controller uses the interrupt type to access a vector from the
interrupt vector table.

running in fully nested mode, so it should use PIO pin to simulate the interrupt-acknowledge pin if necessary.
