Just a thought...
looking at $7B and $A2 bit...Hi,<br /><br />Just a thought...<br /><br />looking at $7B and $A2 bitpatterns:<br />A2 10100010<br />7B 01111011<br /><br />perhaps it's a timing issue? I imagine a square waveform timing diagram for A2 and if the highs were misaligned when read you could easily have the highs 'bleed' into the neighbouring bits, like the first 2 ones on the left side of A2 could end up being the 4 ones in 7B and the single 1 on the right side could end up being 2 ones on the right side of 7B?<br /><br />Of course that could just be coincidence.<br /><br />Regards,<br />Rudi<br />Anonymousnoreply@blogger.com
