Handling Transmission Errors in Operating Mode 0
If the host sends a header block or a block that is not implemented in the protocol (a block type
number higher than 02H), the bootstrap loader reacts in a similar way as described in the figure
above, with the exception, that now a block error code (FEH) is sent to the host. It is up to the host
software to handle this error properly.
The bootstrap loader flowchart of the complete transfer protocol of mode 0 is shown in figure 10-17.
