BDM Command Set Descriptions
This section presents detailed descriptions of the BDM commands.
The V1 BDM command set is based on transmission of one or more 8-bit data packets per operation. Each
operation begins with a host-to-target transmission of an 8-bit command code packet. The command code
definition broadly maps the operations into four formats as shown in
Figure
26-19.
