Question

I have a while loop in C program which was supposed to wait for system to tweak a single bit (bit0) ON and then continue execution. This bit or “flag” is located in a register (reg1). I have been trying to program this using bitwise & operator for masking my register like this.

unsigned int continue;
while(continue != (reg1 & bit0));

I end up getting an error: “Syntax error, multiple markers at this line, expected ‘)’ before ‘;’ token.“

Answer 1

continue is a keyword. You can’t use it as an identifier.

Change the name to something else and see if it works:

unsigned int cont = 0;        //  You also forgot to initialize.
while(cont != (reg1 & bit0));
