Debug Support
32.5.3.1.1
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.
32.5.3.2 Command Sequence Diagrams
The command sequence diagram in
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.

Extension Words as Required
Direction of operand transfer.
0 Data is written to the CPU or to memory from the development system.
1 The transfer is from the CPU to the development system.
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.
