BORM (long d, long i, long n) /*BOR.B #imm3, @(disp12, Rn) */
{
long disp, imm, temp, assignbit;
disp = (0x00000FFF & (long)d);
imm= (0x00000007&(long)i);
temp= (long) Read_Byte (R[n]+disp);
assignbit =(0x00000001<<imm)&temp;
if((T==0)&&(assignbit==0)) T=0;
else T=1;
PC+=4;
}
Examples:
BOR.B #H'5@,(2,R0)
; Before execution: @(R0,2) = H'20, T = 0
; After execution: @(R0,2) = H'20, T = 1
