7.1 Burst mode
When the sensor is operating in burst mode, it will make conversions at specific time intervals. The
programmability of the user is the following:
• Burst speed (T
INTERVAL
) through parameter BURST_DATA_RATE
• Conversion time (T
CONV
) through parameters OSR, OSR2 and DIG_FILT
• Axes/Temperature (MDATA) through parameter BURST_SEL or via the command argument (ZYXT)
Whenever the MLX90393 has made the selected conversions (based on MDATA), the DRDY signal will be set
(active H) on the INT and/or INT/TRG pin to indicate that the data is ready for readback. It will remain high
until the master has sent the command to read out at least one of the converted quantities (ZYXT). Should
