It cannot be described directly in C language. Use the assembly language. When describing in the assembly language in C source, enclose the description with #asm and #endasm. Since an absolute address is used by the assembly language, describe “#pragma romwin 0xXXXX” before the definition line of main function. Describe the end address of ROM window area of each product in 0xXXXX. An example is shown below.
#pragma romwin 0 0xXXXX // Add the description for the end address of ROM window area of each product to 0xXXXX. void main(void) { #asm L ER0, 0000h ; Load the stack pointer stored in the address 0. MOV SP, ER0 ; Set the register content in the stack pointer. #endasm ... }
