Commands
reset (RS)
Command:
This command terminates all active commands. The device settings are reloaded from the
non-volatile memory.
This confirmation is issued for this command (status FFh) instead of a response. The device
resets the hardware and then restarts.
set multiplexed mode (MM)
Command:
Response:
This command switches multiplex mode on and off. In multiplex mode, the R/W heads are
controlled according to the time multiplex process, i.e. only one R/W head is active. The
procedure minimizes mutual interference between R/W heads, allowing two R/W heads to be
mounted side by side.
