Chapter 3 MB91460 Series Basic Information
3.Interrupt Vector Table
Table 3-1 Interrupt Vector Table
Notes:
*1
The ICRs are located in the interrupt controller and set the interrupt level for each interrupt request. An ICR is
provided for each interrupt request.
*2
The vector address for each EIT (exception, interrupt or trap) is calculated by adding the listed offset to the table
base register value (TBR). The TBR specifies the top of the EIT vector table. The addresses listed in the table are
for the default TBR value (0x000FFC00). The TBR is initialized to this value by a reset. After execution of the inter-
nal boot ROM TBR is set to 0x000FFC00.
*3
Used by REALOS
*4
ICR23 and ICR47 can be exchanged by setting the REALOS compatibility bit (addr 0x0C03 : IOS[0])
*5
System reserved
*6
Memory Protection Unit (MPU) support
*7
Only for MB91V460. Please see Chapter 53 Fixed Mode-Reset Vector / BOOT-ROM (Page No.983) for boot
security vectors used on flash devices.
*8
RN resource number used for DMA operation. No number means that this resource interrupt cannot be used to
trigger a DMA transfer.
