Figure 13-4. Command with outgoing data phase
NOTE
• For the outgoing data phase sequence above, the data phase
is really considered part of the response command.
• The host may not send any further packets while it (the
host) is waiting for the response to a command.
• If the ReadMemory Response command packet prior to the
start of the data phase does not contain the
kCommandFlag_HasDataPhase flag, then the data phase is
aborted.
