 		 #160356 - ouput voltage when pin is pulled low
I am using 8051F340 and I am outputting 0 to port 2. The code and the cicuit works fine, but when I accidentally checked the pin voltage I noticed that, 2 out of 8 pins have voltage levels of 0.92 and the rest have 0.4 volts. This is the first time I am seeing 0.92 volts as low, that too for 3.3 volts device. Is this normal?

      Different VOLs?      Raj Nambiar      11/28/08 03:27      
         Why not?      Andy Neil      11/28/08 04:00
