3. Occurs once during powerup. Duration is <5 msec.
4. Occurs during I2C commands for Reset, Read/Write User Registers, Read EID, Read Firmware Version, Read/Write
Thermistor Coefficients and Measure Analog Voltage or Thermistor Temperature. Duration is <50 μs for all commands
except Measure Analog Voltage or Thermistor Temperature, which has <150 μs duration when Thermistor Correction is
enabled.
5. Additional current consumption when HTRE bit enabled. See Section â5.6. Heaterâ for more information.
