Looking at 6809 Assembly Language Programming by Leventhal, and trying to figure out cycle counts. Addressing modes 1) What addressing mode is LDA ,X+ using? I think it's extended direct addressing, which is 5 cycles. 2) leay 1,y is listed as 4+ cycles. How do I know how many the "+" is? Thanks, Lee --- -- - - The 8-bit Coder www.8BitCoder.com
