Consider this simple macro function that checks the status of a timer enable bit:

TimerStatus()
{
  if ((TimerStatreg & 0x01) != 0)/* Checks the status of reg */
    return "Timer enabled"; /* C-SPY macro string used */
  else
    return "Timer disabled"; /* C-SPY macro string used */
}

Save the macro function using the filename extension mac.
