3.1.1 Internal program memory space
counter (PC).
(1) Vector table area
(2) CALLT instruction table area
(3) CALLF instruction entry area

The internal program memory space stores the program and table data. Normally, it is addressed with the program
78K0/KC1 products incorporate internal ROM (mask ROM or 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 signal input 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.
The 64-byte area 0040H to 007FH can store the subroutine entry address of a 1-byte call instruction (CALLT).
The area 0800H to 0FFFH can perform a direct subroutine call with a 2-byte call instruction (CALLF).
