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 38.

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 39.

Note:

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