2.5 Program Memory Space
The program memory space is an area to store the program code, vector table, and Code Options.
The program memory space is specified by 20 bits (CSR:PC) consisting of higher 4 bits as code segment register (CSR)
and lower 16 bits as program counter (PC).
The vector table area is used as the reset vector, hardware interrupt vector, and software interrupt vector. Unused software
interrupt vector area is available as a program code area.
The Code Option area can be used to choose the CPU operation mode, PLL reference frequency, watchdog timer (WDT)
operation mode, unused ROM area access reset enabled/disabled, and remapping function enabled/disabled.
The program code, vector table, and Code Option areas can be read from the ROM window area or the mirror area of the
data memory space by executing the memory access instruction.
Figures 2-2 to 2-14 show the program memory space configuration of each product of the ML620Q1000 series.
