CHAPTER 3 CPU ARCHITECTURE
3.1.1 Internal program memory space
The internal program memory space stores the program and table data. Normally, it is addressed with the program
counter (PC).
78K0R/Lx3 microcontrollers products incorporate internal ROM (flash memory), as shown below.

Capacity
65536 × 8 bits (00000H to 0FFFFH)
98303 × 8 bits (00000H to 17FFFH)
131071 × 8 bits (00000H to 1FFFFH)
The internal program memory space is divided into the following areas.
(1) Vector table area
The 128-byte area 00000H to 0007FH 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. Furthermore, the interrupt jump
address is a 64 K address of 00000H to 0FFFFH, because the vector code is assumed to be 2 bytes.
Of the 16-bit address, the lower 8 bits are stored at even addresses and the higher 8 bits are stored at odd addresses.
