// 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 3 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.
//
// Note that 3 cycles per iteration is valid if SysCtl_delay function resides
// in CxRAM. SxRAM is 2x slower than CxRAM and hence will consume 6 cycles per
// iteration.
