Update Request
-
Used to lock data update in current value
boxes (RWr[n] + 08 to 0D).
This may be used to obtain the current values
of multiple sensor amplifi ers at the same
timing.
The current value is locked while the update
request is held.
The update lock state can be checked by the
current value update lock state (RX[n] + 53).
