MOTOROLA
The sequence is as follows:
• In cycle 1, the development system command is issued (
• In cycle 2, the development system supplies the high-order 16 address bits. The
• In cycle 3, the development system supplies the low-order 16 address bits. The
• At the completion of cycle 3, the debug module initiates a memory read operation.
COMMANDS TRANSMITTED TO THE DEBUG MODULE
RESPONSES FROM THE DEBUG MODULE
READ (LONG)
debug module responds with either the low-order results of the previous command
or a command complete status of the previous command, if no results are required.
debug module returns a not-ready response unless the received command is decoded
as unimplemented, which is indicated by the illegal command encoding. If this
occurs, the development system should retransmit the command.
debug module always returns a not-ready response.
Any serial transfers that begin during a memory access return a not-ready response.

RESULTS FROM PREVIOUS COMMAND
COMMAND CODE TRANSMITTED DURING THIS CYCLE
A not-ready response can be ignored except during a
memory-referencing cycle. Otherwise, the debug module can
accept a new serial transfer after 32 processor clock periods.
