EIT Vector Table

A 1K bytes area from the address indicated in the table base register (TBR) is the vector
area for EIT.
■ EIT Vector Table
The size for each vector is 4 bytes. The relationship between a vector number and a vector address can be
expressed as follows:
vctadr = TBR + vctofs
= TBR + (3FC H - 4 x vct)
vctadr: Vector address
vctofs: Vector offset
vct: Vector number
The low-order two bits of the addition result are always handled as 00.
The area from 000FFC00
Special functions are allocated to some of the vectors.
Table 3.7-3 shows the vector table on the architecture.
