Hi all,

/*
sbit BTN1 at RB1_bit;
sbit PROT at RB2_bit;
sbit  TEST at RB3_bit;

void main() {

TRISB =3D  00001110;
PORTB =3D 00001010;
PROT =3D 0;

if( BTN1 =3D=3D  0){
PROT =3D ~PROT } */

BTN1 is active high and when pressed it shorts the pin to ground. But
when I run the test code above, PROT converts into its complement even
if the button is not pressed. Also when I type if(BTN1 !=3D 1) instead
of if(BTN1 =3D=3D 0), all logic levels are drawn to low, not responsive.
It's a very annoying thing, has anyone encountered such a behavior ?
