14.3.6 Operation of RCV (Recover from Runaway)
If the RTD runs out of control, the RCV (recover from runaway) command may be issued to recover from the
runaway condition without the need to reset the system. The RCV command must always be issued twice in
succession. Also, any command issued immediately following the RCV command must have all of its bits 20–31
set to "1".
