Background Debug Mode (BDM)
5.5.2.2 Transmit Packet Format
The basic transmit packet, Figure 5-14, consists of 16 data bits and 1 control bit.
Table 5-16 describes transmit BDM packet fields.
5.5.3 BDM Command Set
Table 5-17 summarizes the BDM command set. Subsequent paragraphs contain detailed
descriptions of each command. Issuing a BDM command when the processor is accessing
debug module registers using the WDEBUG instruction causes undefined behavior.

Control. This bit is reserved. Command and data transfers initiated by the development system
should clear C.
Contains the data to be sent from the development system to the debug module.
Status. Indicates the status of CPU-generated messages listed below. The not-ready response can
be ignored unless a memory-referencing cycle is in progress. Otherwise, the debug module can
accept a new serial transfer after 32 processor clock periods.
