Hi All,
Regarding the The A4/Serial OUT pin (X2 chips and probably all others?).
I wanted to know *if* i decided to use A4 as an output of some sort, is it likely that my program can lockout the ability for the chip to go back into program mode?
(i *assume* when the chip is in program mode and probably given a higher Vcc voltage it will overide the program running and force programming data handshaking?)
Obviously i would use a 3 pin header to select the A4 pin to connect to either the programmer 'serial OUT' function, or to a control line to an LED, transistor, when the program is normally running...
So, in short, should we use A4?, or should we stay away? ;-)
