:PTRansition? Query PTR register
These commands are used to program the positive transition (PTR) registers. A positive transi-
tion is defined as a 0 to 1 state change in the condition register. Thus, when an event is pro-
grammed for a positive transition, the appropriate bit in the corresponding event register sets
when the corresponding bit in the condition register changes from 0 to 1. For example, if bit B9
of the Positive Transition Register of the Measurement Transition Filter is set, then the buffer
full event is programmed for a positive transition. The BFL bit (B9) in the Measurement Event
Register sets when the trace buffer becomes full. For details on register structure, see paragraph
3.7.
The PTR registers are shown in Figures 3-33A through 3-38A. 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) mea-
surement events for positive transitions, send the following command:
:stat:meas:ptr 544
