Register Name:
Access Type:
• INTLEVEL: Interrupt level associated with this group
Indicates the EVBA-relative offset of the interrupt handler of the corresponding group:
• AUTOVECTOR: Autovector address for this group
Handler offset is used to give the address of the interrupt handler. The least significant bit should be written to zero to give
halfword alignment
