#137323 - DS89C430 - - - - -- ALE SIGNAL |
I AM USING DALLAS DS89C430 MICROCONTROLLER. I am using MTK(microcontroller toolkit ver2.4.04) to download the programms.
1) I am not able to check the ALE signals. I have previously checked this signal and it was comming. But now it is not comming. But the controller is working. I am using MOVX @R0,A instruction. 2) One more thing that i am using 33Mhz xtal osc. My doubt is what value of resistance should be connected between oscll. output and input pin of controller. Normally a series resistance is put. I want to know the logic, reason and criteria of putting appropriate resistance. |

| That\'s not what I said ... | 01/01/70 00:00 | |
| Is this all about 'running without a crystal'? | 01/01/70 00:00 | |
