#93150 - ALE Responding to: ???'s previous message |
Did you try to look the ALE signal in an oscilloscope? it pulses crystal frequency/6 if i'm correct
I always check it and if ALE pules it means the uC is alive |

| Use XTAL2 pin for freq. measurment | 01/01/70 00:00 | |
| Better use 22MHz fundamental + two 27pF | 01/01/70 00:00 | |
