STATus:OPERation:NTRansition
STATus:OPERation:PTRansition
These commands set or read the value of the Operation NTR (Negative-Transition) and PTR
(Positive-Transition) registers. These registers serve as polarity filters between the Operation Enable
and Operation Event registers to cause the following actions. This command is not channel specific, it
applies to the entire mainframe.
႑ When a bit in the Operation NTR register is set to 1, then a 1-to-0 transition of the
corresponding bit in the Operation Condition register causes that bit in the
Operation Event register to be set.
႑ When a bit of the Operation PTR register is set to 1, then a 0-to-1 transition of the
corresponding bit in the Operation Condition register causes that bit in the
Operation Event register to be set.
႑ If the same bits in both NTR and PTR registers are set to 1, then any transition of that
bit at the Operation Condition register sets the corresponding bit in the Operation
Event register.
႑ If the same bits in both NTR and PTR registers are set to 0, then no transition of that
bit at the Operation Condition register can set the corresponding bit in the Operation
Event register.
NOTE : Setting a bit in the PTR or NTR filter can of itself generate positive or negative events in the
corresponding Operation Event register.
