• Four interrupt control registers (ICR1–ICR4), which are used to assign interrupt
• The interrupt source register (ISR) allows reading the instantaneous value of each
• The programmable interrupt transition register (PITR) specifies the triggering
• The programmable interrupt wakeup register (PIWR) specifies which interrupt
• The programmable interrupt vector register (PIVR) specifies which vector number
