Vectored Interrupt Controller

18.2.2.12 Vector Control Registers (VECTCTRLx)

There are 16 Vector Control Registers, designated VECTCTRL0 through VECTCTRL15.
Software uses these registers to assign the desired interrupt to the desired interrupt vector.
The interrupt number from Table 18-1 (in hexadecimal) is programmed to the IntSource
bits, and the 'E' bit is set to enable that vector.
Vectored interrupts are only generated if the interrupt is enabled in the INTENABLE Register,
and the interrupt is programmed to generate an IRQ interrupt in the INTSELECT Register.
This prevents multiple interrupts from being generated by a single request if the controller is
incorrectly programmed.
