A.4
EOF when using one subcarrier
A.4.1
High data rate
For the Fast commands, the EOF comprises a logic 0 that includes four pulses at
423.75 kHz and an unmodulated time of 9.44 µs, followed by 12 pulses at 423.75 kHz
(fC/32) and an unmodulated time of 37.76 µs, as shown in Figure 90.

A.4.2
Low data rate
For the Fast commands, the EOF comprises a logic 0 that includes 16 pulses at 423.75 kHz
and an unmodulated time of 37.76 µs, followed by 48 pulses at 423.75 kHz (fC/32) and an
unmodulated time of 113.28 µs, as shown in Figure 91.

Note:
For SOF and EOF in fast commands, bit coding using two subcarriers is not supported.
