BIT NAME DESCRIPTION
15:11 TMM[4:0]
Temperature Measurements: These bits dene the number of temperature measurement cycles to
be executed when the EVTMG1 or EVTMG3 command is executed.
Cycles = 1+ TMM[4:0]

10 CAL_USE
Calibration Usage: This bit, when set, causes the MAX35101 to use the calibration data in the
CalibrationInt and CalibrationFrac registers during measurement, averaging and accumulation
of data while executing the EVTMG commands. All time measurements are scaled using the
calibration factors as described by the calibrate command.
9:7 CAL_CFG[2:0]
Calibration Conguration: These bits dene the point in the EVTMGx cycle/sequence where the
automatic calibration command is executed.
CAL_CFG[2:0]
DESCRIPTION
DURING EVTMGX SEQUENCES, AUTOMATIC EXECUTION OF
THE CALIBRATE COMMAND OCCURS AT:
000b through 011b Autocalibration disabled
100b
