8.5.9
The QVER command queries the version of the
programming executive software stored in test
memory. The “version.revision” information is returned
in the response’s QE_Code using a single byte with the
following format: main version in upper nibble and
revision in the lower nibble (i.e., 0x23 means version
2.3 of programming executive software).
Expected Response (2 words):
0x1BMN (where “MN” stands for version M.N)
0x0002
9.0
9.1
The programming executive sends a response to the
programmer for each command that it receives. The
response indicates if the command was processed
correctly, and includes any required response, or error,
data.
The programming executive response set is shown in
Table
and description for each response. The response
format is described in

9.2
All programming executive responses have a general
format consisting of a two-word header and any
required data for the command.
9.2.1
The Opcode is a 4-bit field in the first word of the
response. The Opcode indicates how the command is
processed (see
processed successfully, the response opcode is PASS.
If there is an error in processing the command, the
response opcode is FAIL, and the QE_Code indicates
the reason for the failure. If the command sent to
the programming executive is not identified, the
programming executive returns a NACK response.
9.2.2
The Last_Cmd is a 4-bit field in the first word of
