Details 
These commands are used to program the positive transition (PTR) registers. A positive transition is 
defined as a 0 to 1 state change in the condition register. Thus, when an event is programmed 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 transition filter transition filter is set, then the buffer full event is programmed 
for a positive transition. The BFL bit (B9) in the transition filter event register sets when the trace 
buffer becomes full. For details on register structure, see Status structure. 
The PTR 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 positive 
transitions, send the following command: 
:stat:meas:ptr 544 
Where:   BFL (Bit B9) = Decimal 512 
  RAV (Bit B5) = Decimal32 
        <NRf> = 544
