Chapter 5Interrupt ControllerV - 10 Control Registers5.2.3 Interrupt Vector RegisterThe interrupt vector register is a register that stores the lower 16 bits of the starting address of the processing pro-gram for the accepted level interrupts. The starting addressees of level 0 to 6 of the level interrupts correspond toIVAR0 to IVAR 6. When an interrupt occurs, control is transferred from the upper 16 bits to”0x’4000” and fromthe lower 16 bits to the 32-bit address which is comprised of IVARn corresponding to the interrupt level.Table:5.2.4 Interrupt Level and Interrupt Vector Register■ Interrupt Vector Register 0 (IVAR0: 0x00008000) [16-bit access register]■ Interrupt Vector Register 1 (IVAR1: 0x00008004) [16-bit access register]Interrupt level Interrupt vector register0 IVAR01 IVAR12 IVAR23 IVAR34 IVAR45 IVAR56 IVAR6bp 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0Flag IVAR015IVAR014IVAR013IVAR012IVAR011IVAR010IVAR09IVAR08IVAR07IVAR06IVAR05IVAR04IVAR03IVAR02IVAR01IVAR00At reset x x x x x x x x x x x x x x x xAccess R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/Wbp 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0Flag IVAR115IVAR114IVAR113IVAR112IVAR111IVAR110IVAR19IVAR18IVAR17IVAR16IVAR15IVAR14IVAR13IVAR12IVAR11IVAR10At reset x x x x x x x x x x x x x x x xAccess R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W R/W
