"When Atmel brought out the first flash '51s (their first '51s) they got to rev S before the chip worked as specified."
I know, that the first AT89C52/55 and AT89S53/8252 has a bug, if P1.0 was used as square wave output, then any read-modify-write to the other P1 pins disturb the square wave. Know anybody, if this bug was removed finally ? Peter |
