#150262 - Xtal2 (pin 4) AT89S2051 problem |
Hi, I just try using AT89S2051. But I found some problem with Xtal2 (pin 4) that usually can work as Osc output to cascade another MCU. I checked with logic probe on that pin, it has no pulse.
And I confuse about the function of Xtall oscilator bypass fuse. When I try enable and disable that fuse, only change the state of pin 4. Is there anyone ever find out this problems? Please let me know. Thanks Suhandry Salim |
