3.1.1 Internal program memory space
counter (PC).
(1) Vector table area
58
The internal program memory space stores the program and table data. Normally, it is addressed with the program
78K0/KE2 products incorporate internal ROM (flash memory), as shown below.
The internal program memory space is divided into the following areas.
The 64-byte area 0000H to 003FH is reserved as a vector table area. The program start addresses for branch
upon reset or generation of each interrupt request are stored in the vector table area.
Of the 16-bit address, the lower 8 bits are stored at even addresses and the higher 8 bits are stored at odd
addresses.
