Hi,
I'm working on a HW assignment and was wondering if someone could assist me. The assignment is to write a program to copy the first 16 code memory locations starting with 0000h to XRAM starting with memory location 2000h. The program I wrote works for the first 10 locations only. It's got me very frusterated and any help would be appreciated.
