executed

76 Error code returned after data check command or MDL command was executed
Note 1. Processing is normal when 7B as an end code has been returned. If the volt -
age of the battery is low and no communications are available, an error
response such as 72 will be returned.
2. When
a polling auto command is sent, the ID Controller promptly returns a
“command received” response (74).
3. When a polling auto command is sent to query processing results, the ID
Controller returns a “DC near” response (74) if the DC is not present. Refer
to 6-3 Error Lists for more details on the errors.
3-5 Communication T ime
The time required for communications varies with the DC memory type (SRAM
or EEPROM). Furthermore, if the memory is EEPROM, communications time
varies with the slave communications mode setting. The communications time
consists of TAT (turn around time) and slave communications time. TAT is the
time required for the host computer to receive a response after it has finished
sending a command. Slave communications time is the time required for com -
munications between the R/W Head and DC and is exclusive of host commu-
nications
time. Slave communications time is used as a reference when calcu -
lating the moving speed of an auto command.
