Exercise caution in the following points when using this command.
1. In order to avoid damage to the results of SEND
DIAGNOSTIC command execution (response data) from a
command issued by another INIT during the interval until this
command is issued, either this command should be executed
after the IDD is reserved.
2. Response data are valid only when "0" is specified in the
"SelfTest (self test)" bit and after a SEND DIAGNOSTIC
command which specifies a specific operation in the parameter
list is executed, with the IDD transferring response data
showing the execution results of the latest SEND
DIAGNOSTIC command. Also, even if this command is
executed, the response data in not cleared, and remains valid
until the next SEND DIAGNOSTIC command is executed.
3.
If this command is issued when valid response data do not exist,
the IDD transfers a maximum of 4 bytes of X '00' data to the INIT.
