;–––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––––;
We must wait for transmission to complete before writing next word to the SDTR.;
TLV5614/04 interface does not allow the use of burst mode with the full packet; rate, as
we need a CLKX -ve edge to clock in last bit before FS goes high again,; to allow SPI
compatibility.
