7.1 Response Syntax
The following table shows the types of responses for the various commands described in
the previous chapter.
The CX returns a response (affirmative/negative response) to a command that is delimited
by a single terminator. The controller should follow the one command to one response
format. When the command-response rule is not followed, the operation is not guaranteed.
