D7 (More):
Data state indication bit, which is set by the PS2000A and valid when the
PS2000A responds to a READ command from the Network Server.
D7=1: The object has not finished transmitting the data and the Network Server should
continue to transmit the READ command to read the data.
D7=0: The data transmission of the object has been finished.
D6 (Error):
Flag bit indicating command error which is set by the PS2000A and valid
in all return commands.
D6=0: Indicating that the command sent from the Network Server has been successfully
executed by the PS2000A.
D6=1: Indicating that the command sent from the Network Server cannot be executed by
the PS2000A.
D5 (NO_ACK):
ACK control bit. The Network Server sets this bit.
D5=1: Indicating that the PS2000A should execute the command of the Network Server,
without reporting the execution results back to the server.
D5=0: Indicating that the PS2000A should execute the command of the Network Server
and report the execution results to the server.
