The appropriate bit is set to 1. For example, to stop the drive bit two is set (send 0004H). To start the drive
send 0008H. Setting update buffers bit, enables to start the drive using downloaded data. Locking security
disables the serial drive control, the communications watchdog timer and prevents any further writing to
control or parameter registers.
