*1 : ICRs are registers built in the interrupt controller to set interrupt levels for individual interrupt requests.
*2 : The TBR is the register holding the start address of the EIT vector table.
Note: The 1 Kbyte area from the TBR address is the EIT vector area.

Vctadr
The ICRs are provided for the different interrupt levels.
The TBR value and the offset value preset for each EIT source are added together to be the vector address.
The vector size is 4 bytes and the relationship between vector number and vector address is expressed as
follows:
vctadr : vector address
