// Macro to call SysCtl_delay() to achieve a delay in microseconds. The macro
// will convert the desired delay in microseconds to the count value expected
// by the function. \b x is the number of microseconds to delay.
// The SysCtl_delay() function takes around 6 cycles per iteration plus 9  
// cycles of overhead which needs to be accounted for when converting the  
// microseconds delay into the number of delay loop iterations passed to the 
// SysCtl_delay() function.
