Fig.13 Waveforms showing SO minimum pulse width and maximum pulse frequency, in high-speed shift-out

burst mode.

Note to Fig.13

In the high-speed mode, the burst-out rate is determined by the minimum shift-out HIGH and shift-out LOW

specifications. The DOR flag is a don't care condition and an SO pulse can be applied without regard to the flag.
