STATus
STATus:OPERation:NTRansition
STATus:OPERation:NTRansition <transition_mask> sets bits in the Negative
Transition Filter (NTF) register. When a bit in the NTF register is set to one, the
corresponding bit in the Condition register must change from a one to a zero in order
to set the corresponding bit in the Event register. When a bit in the NTF register is
zero, a negative transition of the Condition register bit will not change the Event
register bit.
Parameters
Comments •
may be sent as decimal, hex (#H), octal (#Q), or binary (#B).
•
If both the STAT:OPER:PTR and STAT:OPER:NTR registers have a
corresponding bit set to one, any transition, positive or negative, will set the
corresponding bit in the Event register.
•
If neither the STAT:OPER:PTR or STAT:OPER:NTR registers have a
corresponding bit set to one, transitions from the Condition register will have
no effect on the Event register.
