Details
These commands are used to program the negative transition (NTR) registers. A negative transition is
defined as a 1 to 0 state change in the condition register. Thus, when an event is programmed for a
negative transition, the appropriate bit in the corresponding event register sets when the
corresponding bit in the condition register changes from 1 to 0. For example, if Bit B9 of the Negative
Transition Register of the transition filter transition filter is set, then the buffer full event is
programmed for a negative transition. The BFL bit (B9) in the transition filter event register sets when
the trace buffer is no longer full. For details on register structure, see Section 13.
The NTR registers are shown below. Included is the decimal weight of each bit. The sum of the
decimal weights of the bits that you wish to set is the parameter (<NRf>) that is sent with the
command. For example, to program RAV (B5) and BFL (B9) measurement events for negative
transitions, send the following command:
:stat:meas:ntr 544
Where: BFL (Bit B9) = Decimal
RAV (Bit B5) = Decimal
<NRf> =
