Background Debug Mode (BDM)
5.5.3.1.1 Extension Words as Required
Some commands require extension words for addresses and/or immediate data. Addresses
require two extension words because only absolute long addressing is permitted. Longword
accesses are forcibly longword-aligned and word accesses are forcibly word-aligned.
Immediate data can be 1 or 2 words long. Byte and word data each requires a single
extension word and longword data requires two extension words.
Operands and addresses are transferred most-significant word first. In the following
descriptions of the BDM command set, the optional set of extension words is defined as
address, data, or operand data.
5.5.3.2 Command Sequence Diagrams
The command sequence diagram in Figure 5-19 shows serial bus traffic for commands.
Each bubble represents a 17-bit bus transfer. The top half of each bubble indicates the data
the development system sends to the debug module; the bottom half indicates the debug
module’s response to the previous development system commands. Command and result
transactions overlap to minimize latency.

Operand data size for sized operations. Addresses are expressed as 32-bit absolute values.
Note that a command performing a byte-sized memory read leaves the upper 8 bits of the
response data undefined. Referenced data is returned in the lower 8 bits of the response.
