Power up reset

[Acetronics2]

Hi,

During power up ...

all pins are INPUTS ( say floating ! ) ... till you turn them to outputs.

So ...

1) place some pullup or pulldown ( to suit your application ) resistors to fix the outputs ( may be inputs too, depends on circuitry ahead ... ) levels while they are " uncontrolled "

2) program output and input levels required ( PORTx = % 11001010 i.e )

3) THEN program inputs and outputs ( TRISx = % 00110110 i.e )

This way ... outputs are fully under control ... Even if Pic is taken off from its socket !!!
