Just a quick question regarding memory contention on the SAM and its effect on JP and the *unconditional* JR instruction.
Z80 timing lists state that JP takes 10 T-States whereas an *unconditional* JR takes some 12 T-States. However, does the SAM's memory contention make all *unconditional* JRs faster (or as fast) as the JP due to the JP needing another memory access? Just a simple "Yes, always use JR over JP in unconditional cases" - or - "No, stick with JP as it's faster!" please guys, as my head explodes reading too much hardware-based theory! Cheers... Chris.
