Fig. 4.3: Scale Status register
4.5. SCALE INCREMENT
(Base a %56 r/w)
If the module is configured with 16 independent channels, a VME access (read or write) to this
location increases all the channels (same as the TEST signal).
4.6. VETO SET/RESET
(Base a %52, Base a %54 r/w)
A VME access (read or write) to the address Base + % 52 sets the VME VETO; the scales are not
able to count.
A VME access (read or write) to the address Base + % 54 clears the VME VETO; If no external
VETO is present, the scales are able to count.
4.7. CLEAR SCALES
(Base a %50 r/w)
A VME access (read or write) to this location causes the following operation:
•
all the scales are cleared;
•
the VME interrupt request (if asserted), is removed (RORA INTERRUPTER);
•
the VME interrupt generation is disabled.
