For the Fast commands, the SOF comprises an unmodulated time of 113.28 µs, followed by

48 pulses at 423.75 kHz (fC/32), and a logic 1 that includes an unmodulated time of 37.76 µs

followed by 16 pulses at 423.75 kHz as shown in Figure 27.

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 28.

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