// Interrupt controller management

// This chip has a programmable interrupt vector base which is different
// from the vector base  register (VBR). All interrupts from the interrupt
// controller are offset from the programmable interrupt vector register
// (PIVR). However, the only legal value is 64.

// Vector numbers defined by the interrupt controller.
// These are all relative to the interrupt vector base number.
