I’m having trouble getting this subroutine I’m writing to work. Basically, I am trying to have a subroutine where I would set
R0 to a value in some
array (R3) with an offset of
R0_ORIGINAL .FILL 0 R1_ORIGINAL .FILL 0 R2_ORIGINAL .FILL 0 R3_ORIGINAL .FILL 0 LOAD ST R0, R0_ORIGINAL ST R1, R1_ORIGINAL ST R2, R2_ORIGINAL ST R3, R3_ORIGINAL AND R0, R0, #0 ADD R0, R0, R2 BRz SKIP AND R3, R3, #0 LD R3, FIFTY ADD R1, R1, R3 SKIP AND R3, R3, #0 LEA R3, CIPHER_ARRAY STR R0, R3, R1 LD R0, R0_ORIGINAL LD R1, R1_ORIGINAL LD R2, R2_ORIGINAL LD R3, R3_ORIGINAL RET CIPHER_ARRAY .BLKW #100 FIFTY .FILL #50
This is the line I’m trying to get to work :
STR R0, R3, R1
It gives me the error :
Expected 6 bit signed number, but found ‘R1’ instead.
