/**
* TMC2208 Direction-Flip Delay
*
* Some TMC2208 / TMC2208_STANDALONE drivers may require a short delay after a DIR change
* to prevent a standstill error, especially when using stealthChop (the standalone default).
*
* When enabled for an axis, FT Motion will hold that axis for > 750µs after a DIR change
* by holding its trajectory coordinate constant for a multiple of FTM_TS frames. For the
* default FTM_FS = 1000, it is a single 1ms frame.
*
* Other axes keep moving normally, and the wait is canceled if the axis flips again.
*
* Disable if you use spreadcycle
