FIGURE 16-1:
The command in the Opcode field must match one of
the commands in the command set that is listed in
Table 16-3. Any command received that does not
match a command the list returns a NACK response,
as shown in Table 16-2.
The PE uses the command Length field to determine
the number of bytes to read from or to write to. If the
value of this field is incorrect, the command is not be
properly received by the PE.
16.2.2
The PE response set is shown in Table 16-2. All PE
responses have a general format consisting of a 32-bit
header and any required data for the response (see
Figure 16-2).

Last_Cmd is a 16-bit field in the first word of the
response and indicates the command that the PE pro-
cessed. It can be used to verify that the PE correctly
received
transmitted.
16.2.2.2
The response code indicates whether the last
command succeeded or failed, or if the command is a
value that is not recognized. The response code values
are shown in Table 16-2.

The response header may be followed by optional data
in case of certain commands such as read. The num-
ber of 32-bit words of optional data varies depending
on the last command operation and its parameters.
