6.5. Temperature Sensor
In Single measurement mode, Continuous measurement mode 1, 2, 3, 4, or External trigger measurement mode is set,
AK09912 can measure temperature sensor together with magnetic sensor. When temperature sensor is enabled (TEM =“1”),
temperature sensor measurement is started together with magnetic sensor measurement. In Continuous measurement mode
1, 2, 3 or 4, temperature sensor measurement is started at every 8 measurements of magnetic sensor measurement. In Single
measurement mode or External trigger measurement mode, temperature sensor measurement is stared at every measurement
of magnetic sensor measurement. When user wants to change temperature sensor measurement enables or disables, set to
Power-down mode is required before change temperature sensor measurement.
Default TEM register is “disable” (TEM=“0”).
6.6. Noise Suppression Filter (NSF)
In Single measurement mode, Continuous measurement mode 1, 2, 3, 4 or External trigger measurement mode, output from
the magnetic sensor can be filtered to suppress the noise. This filter name is Noise Suppression Filter (NSF). There are three
optional filter extents. When NSF[1:0]= “00”, NSF is “disable” and output magnetic data is not filtered. When NSF[1:0]=
“01”, NSF extent is “Low” and output magnetic data is filtered mildly. When NSF[1:0]= “10”, NSF extent is “Middle” and
output magnetic data is filtered moderately. When NSF[1:0]= “11”, NSF extent is “High” and output magnetic data is
filtered strongly.
NSF register can be changed in Power-down mode only.
Default NSF register is “disable” (NSF[1:0]= “00”).
