BIT NAME DESCRIPTION
15:12 TDF[3:0]
TOF Difference Measurement Frequency: These bits dene the rate at which TOF_DIFF
measurements are executed when the EVTMG1 or EVTMG2 command is executed.
Rate = 0.5s + (TDF[3:0] x 0.5s)
TDF[3:0] (decimal) RATE
0 0.5 s
1 1.0s

14 7.5 s
15 8.0 s
11:7 TDM[4:0]
TOF Difference Measurements: These bits dene the number of TOF_DIFF measurement cycles
to be executed when the EVTMG1 or EVTMG2 command is executed.
Cycles = 1+ TDM[4:0]
TDM[4:0] (decimal) CYCLES
0 1
1 2

30 31
31 32
6:1 TMF[5:0]
Temperature Measurement Frequency: These bits dene the time delay between temperature
cycle measurements. It is a start-cycle to start-cycle time duration at which temperature
measurement cycles are executed when the EVTMG1 or EVTMG3 command is executed.
Rate = 1.0s + (TMF[3:0] x 1.0s)
TMF[5:0] (decimal) RATE
0 1 s
