Result
In cycle 3, the development system supplies the low-order 16 address bits. The debug module
always returns a not-ready response.
At the completion of cycle 3, the debug module initiates a memory read operation. Any serial
transfers that begin during a memory access return a not-ready response.
Results are returned in the two serial transfer cycles after the memory access completes. For any
command performing a byte-sized memory read operation, the upper 8 bits of the response data are
undefined and the referenced data is returned in the lower 8 bits. The next command’s opcode is
sent to the debug module during the final transfer. If a memory or register access is terminated with
a bus error, the error status (S = 1, DATA = 0x0001) is returned instead of result data.
Command Set Descriptions
The BDM status bit (S) is 0 for normally completed commands; S = 1 for
illegal commands, not-ready responses, and transfers with bus-errors.
