HFD
H9696: resets the drive unit
As the drive unit is reset at start of communication by the computer, the drive
unit cannot send reply data back to the computer.

H9966: resets the drive unit
When data is sent normally, ACK is returned to the computer and then the
drive unit is reset.

HFC
All parameters return to the initial values.
Whether to clear communication parameters or not can be selected
according to data. (
: Clear,
: Not clear)
for parameter clear, all clear, and communication
parameters.
When clear is executed for H9696 or H9966, communication-related
parameter settings also return to the initial values. When resuming
operation, set the parameters again.
Executing clear will clear the instruction code HEC, HF3, and HFF settings.
In the password locked status
(refer to page 162)
, only H9966 and
H55AA (all parameter clear) are valid.
Turning OFF the power supply while clearing parameters with H5A5A or H55AA
also clears the communication parameter settings back to the initial values.
