3.1.1 Internal program memory space
(1) Vector table area
The internal program memory space stores the program and table data.
78K0R/KE3 products incorporate internal ROM (flash memory), as shown below.
The internal program memory space is divided into the following areas.
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.
