Valid time is used to set the time (ms) to control the command output signal. The command
output signal is controlled based on the control scheme described in section 11.4.5(iv)-5 for
the setting time after receiving General command, and is reset by communication side after
the set time. However, if the time is set to “0”, the control is not reset and is continued. Set
the time with a margin for interface of other applications.
ACK/NACK / Ext
This setting is used to enable the extension setting of Command ACK/NACK response
scheme or not. If “Ext” is not specified (Ext check box is not checked.), Command NACK (in
cases of (1)–(3) of the section 11.4.5(iii) and Command ACK (in case of others) respond
according to the default response. If “Ext” is specified, the setting of Command ACK/NACK
described later is enabled and the response scheme can be customized. When required the
stricter handshake by using Command ACK/NACK, it is better to specify the “Ext”. This
setting is not influenced by the control scheme of the command output signal.
Signal ACK Name/Signal ACK Desc./Signal NACK Name/Signal NACK
Desc./Inverse
“ACK Sig” and “NACK Sig” are used to set the Data ID for judgment of command response.
(Hereafter, these are described as “command response signal”.) “Inverse” is used to reverse
the logic of the command response signal, and “Timeout” is used to set the timeout time for
judgment of command response. Under specified “Ext” (Ext check box is checked.),
Command ACK or Command NACK responds based on the logic of command response
signal against General command.
When the command response signal is treated as two signals (ACK Sig  NACK Sig),
the judgment scheme is shown as the following table by the combination of the receiving
command DCO and Inverse setting. The judgment timing is when (1), (2), (3) or (4) in Table
11.4-15 is established. If the neither (1), (2), (3) nor (4) is established (that is ACK sig =
NACK Sig = 1 or ACK sig = NACK Sig = 0) for the period from the command receiving to
the timeout setting time, Command NACK responds at that time.
For example, when the DCO=On command is received under “Inverse” no-checked,
Command ACK responds in case of “ACK Sig = 0” and NACK Sig = 1”.
