• Description: 8-bit Single-chip Microcontrollers
• Manufacturer: Renesas Electronics Corporation.

3.1.1 Internal program memory space
counter (PC).
(1) Vector code area
80
The internal program memory space stores the program and table data. Normally, it is addressed with the program
78K0/Dx2 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 code area. The program start addresses for branch
upon reset signal input or generation of each interrupt request are stored in the Vector code 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.
