3.1.1 Internal program memory space
program counter (PC).
The internal program memory space stores programs and table data. This space is usually addressed by the
Each model in the PD780988 Subseries is provided with the following internal ROM (or flash memory).
The following areas are allocated to the internal program memory space.
(1) Vector table area
(2) CALLT instruction table area
The 64-byte area of addresses 0000H to 003FH is reserved as a vector table area. This area stores program
start addresses to which the program branches when the RESET signal is input or when an interrupt request
is generated. Of a 16-bit program start address, the lower 8 bits are stored in an even address, and the higher
8 bits are stored in an odd address.
The subroutine entry address of a 1-byte call instruction (CALLT) can be stored in the 64-byte area of
addresses 0040H to 007FH.
