// 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.
