CHAPTER 4  RESET AND "EIT" PROCESSING

■

Vector tables are located in the main memory, occupying an area of 1 Kbyte beginning with the address

shown in the TBR. These areas are intended for use as a table of entry addresses for "EIT" processing,

however in applications where vector tables are not required, this area can be used as a normal instruction

or data area.

Figure 4.2-2 shows the structure of the vector table. (Example of 32-source)
