#150755 - 1 external Osc drive 2 Microcontrollers, possible? Responding to: ???'s previous message |
So, from the datasheet of AT89LP2052, I saw that I can't use Xtal2 pin to drive Xtal1 pin on another microcontroller. Now I use Xtal Oscilator 22.18MHz with AT89S2051. I wish I could drive both microcontroller with 1 external oscilator. Before when I use AT89C2051 I can do this method. IS there any other way? or I need "split" the output and feed into both Xtal1 pins? I need use this 'S' type as it could x2 mode to speed up. I still can't find AT89LP2052 series in here (Taiwan).
Thank you, Suhandry Salim |
