problem using input C.5 on PICaxe 08M2

I'm using a 08M2.
I've used up pins C.0 - C.4 and everything works nicely.
Now I want to have one more digital input, but I find that connecting anything except ground to C.5 upsets the 08M2. I cannot even download a program to it - error massage: Verification error - 0x00 transmitted but 0xFFFFFFF0 received at byte 0.
I've tried swapping the 08M2 and get the same problem.
Is there a known problem with C.5? Any suggestions?

Hi,

Welcome to the forum. Pin C.5 puts the PICaxe into Programming mode whenever it is taken high. To avoid this, you need a DISCONNECT command at the top of your program. Note that the pin must not be taken high until AFTER the PICaxe has booted up each time. Also, you either need to put a RECONNECT command when (if) the program finishes (assuming it doesn't loop continuously) or use the "Hard Reset" procedure to download a new program.

Cheers, Alan
