CHAPTER 2 MEMORY ARCHITECTURE
■
Contents of Vector Table Areas
A vector table is composed of entry addresses for each of the "EIT" processing programs. Each table
contains some values whose use is fixed according to the CPU architecture, and some that vary according
to the types of built-in peripheral circuits present. Table 2.1-1 shows the structure of a vector table area.
*: Even when the "TBR" value is changed, the reset vector remains the fixed address "000FFFFC
H
".
■
Vector Table Area Initial Value
After a reset, the value of the table base register (TBR) is initialized to "000FFC00
H
", so that the vector
table area is between addresses "000FFC00
H
" and "000FFFFF
H
".
