High data rate

The SOF comprises 27 pulses at 484.28 kHz (fC/28), followed by 24 pulses at 423.75 kHz

(fC/32), and a logic 1 that includes 9 pulses at 484.28 kHz followed by 8 pulses at

423.75 kHz as shown in Figure 27.

For the Fast commands, the x2 mode is not available.

Low data rate

The SOF comprises 108 pulses at 484.28 kHz (fC/28), followed by 96 pulses at 423.75 kHz

(fC/32), and a logic 1 that includes 36 pulses at 484.28 kHz followed by 32 pulses at

423.75 kHz as shown in Figure 28.

For the Fast commands, the x2 mode is not available.
