3. The vector numbers and vector table address offsets for each on-chip peripheral
4. Vector numbers are set in the on-chip vector number register. See section 5.3, Register
5. The same vector number, 10, is generated for a DMAC DMA address error and an E-
module interrupt are given table 5.4, Interrupt Exception Vectors and Priorities, in
section 5, Interrupt Controller.

Controller, for more information.
DMAC DMA address error. (See table 4.3 (a).)
Both the address error flag (AE) in the DMAC’s DMA operation register (DMAOR) and
the address error control bit (AEC) in the E-DMAC’s E-DMAC operation control register
(EDOCR) must therefore be read in the exception service routine to determine which
DMA address error has occurred.
Calculating Exception Vector Table Addresses
Vector Table Address Calculation
(Vector table address) = (vector table address offset)
(Vector table address) = VBR + (vector table address offset)
= (vector number)
= VBR + (vector number)
