Figure 17.82 Boot Program States
Bit-Rate-Adjustment State
The bit rate is calculated by measuring the period of transfer of a low-level byte (H'00) from the
host. The bit rate can be changed by the command for a new bit rate selection. After the bit rate
has been adjusted, the boot program enters the inquiry and selection state. The bit-rate-adjustment
sequence is shown in figure 17.83.
