The Last_Cmd is a 4-bit field in the first word of
the response and indicates the command that the

command at a time, this field is technically not required.
However, it can be used to verify that the programming
executive correctly received the command that the
programmer transmitted.
6.3.1.3
The QE_Code is a byte in the first word of the
response. This byte is used to return data for query
commands and error codes for all other commands.
When the programming executive processes one of the
two query commands (QBLANK or QVER), the returned
opcode is always PASS and the QE_Code holds the
query response data. The format of the QE_Code for
both queries is shown in

The response length indicates the length of the
programming executive’s response in 16-bit words.
This field includes the 2 words of the response header.
With the exception of the response for the read
commands, the length of each response is only 2
words.
The response to the read commands uses the packed
instruction word format described in
