#135076 - '48 the jumps are never relative Responding to: ???'s previous message |
Jan,
After reading this statement i had to check. I had forgotten this completely. It was the '48's "page" addressing that always bothered me. Any complete executable that was a page or less was worth an extra 5 points. Your assembler could handle the paging symbolically but hand-patching with your intel PROMPT-48 was a bit painful. Switching to the '51 from '48 was liberating. The '48's R0/R1 indirection remained, as did most accumulator ops including the "swap". The IRAM vs. XRAM of the '51 was a super set of the '48's and your '48 XRAM @R0/1 remained. The integrated hardware and the logic of addressing bits/RAM/SFRs, to some studying. regards, p |
