#190352 - Done checking already
Responding to: Jim Granville's previous message
1. I have probed EA pin on CRo, its +5V constantly

2. Made a program to toggle port that's it.
void main
{
while(1)
{
P1 = ~P1;
}
}



3. Program made in keil,
Option checked in keil options: for using on chip rom only.



4. One thing I don't understand on PSEn pin I saw same frequency as on ALE pin.
I had checked for shrting, any coupling nearby but found none
