Bit-rate matching state
In bit-rate matching, the boot program measures the low-level intervals in a signal carrying H'00
data that is transmitted by the host, and calculates the bit rate from this. The bit rate can be
changed by the new-bit-rate selection command. On completion of bit-rate matching, the boot
program goes to the inquiry and selection state. The sequence of processing in bit-rate matching is
shown in figure 17.16.
