5.1.1 Internal program memory space
program counter (PC).
(1) Vector table area
(2) CALLT instruction table area
(3) CALLF instruction entry area
The internal program memory space contains the program and table data. Normally, it is addressed with the
The PD780078, 780078Y Subseries incorporate internal ROM (mask ROM or flash memory), as listed below.
The internal program memory space is divided into the following three areas.
The 64-byte area 0000H to 003FH is reserved as a vector table area. The program start addresses for branch
upon RESET input or interrupt request generation 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.
Note
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).
