Event Timing Mode 2

The EVTMG2 command execution causes the TOF_DIFF

command to be executed automatically with program-

mable repetition rates and programmable total counts as

shown in Figure 7.

During execution of the EVTMG2 command, each TOF_

DIFF command execution cycle causes the MAX35101

to compute a TOF_DIFF measurement (AVGUP register

minus AVGDN register) as well as the running average of

TOF_DIFF measurements (TOFF_DIFF_AVG register).

The setting of the TDF[3:0] bits in the Event Timing 1 reg-

ister selects the rate at which TOF_DIFF commands are

executed. The setting of the TDM[4:0] bits in the Event

Timing 1 register determines the number of TOF_DIFF

measurements to be taken during the sequence.

Once all of the TOF_DIFF measurements in the sequence

are captured, the TOF_DIFF_AVG register contains the

average of the differences of the resultant AVGDN and

AVGUP Results register content of each TOF_DIFF

measurement. After the TOF_DIFF_AVG registers are

updated, the TOF_EVTMG bit is set in the Interrupt Status

Event Timing Mode 3

The EVTMG3 command execution causes the tem-

perature command to be executed automatically with

programmable repetition rates and programmable total

counts (Figure 9).

During execution of the EVTMG3 command, each

Temperature command execution cycle computes the

running average of the measurement of each tempera-

ture port. The results are provided in the Tx_AVGInt and

TxAVGFrac Results registers.

The setting of the TMF[5:0] bits in the Event Timing 1 reg-

ister selects the rate at which temperature commands are

executed. The setting of the TMM[4:0] bits in the Event

Timing 2 register determines the number of temperature

measurements to be taken during the sequence.

Once all of the temperature measurements in the sequence

are captured Tx_AVGInt and TxAVGFrac Results regis-

ters contains the average of all the temperature measure-

ments in the sequence. After these registers are updated,

the Temp_EVTMG bit is set in the Interrupt Status register

and the INT pin asserts (if enabled).
