The address ConfigRegister1 consists of control bits for configuring the analog and digital parts:
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
Config register bit meaning
1 0 0 - IIR (100%) a1=1, b1=0
1 0 1 - IIR (80%) a1=0.8, b1=0.2
1 1 0 - IIR (67%) a1=0.666, b1=0.333
1 1 1 - IIR (57%) a1=0.571, b1=0.428
0 0 0 - IIR (50%) a1=0.5, b1=0.5
0 0 1 - IIR (25%) a1=0.25, b1=0.75
0 1 0 - IIR (17%) a1=0.166(6), b1=0.83(3)
1 1 1 - IIR (13%) a1=0.125, b1=0.875
0 - Repeat sensor test "OFF"
1 - Repeat sensor test "ON"
0 0 - Ta on PWM channel 1, Tobj1 on PWM channel 2
0 1 Not Valid
1 0 Not Valid
1 1 - Tobj1 on PWM channel 1
1 - This bit should always be set to '1'
M - Melexis reserved - Do not change
0 0 0 - FIR = 8 not recommended
0 0 1 - FIR = 16 not recommended
0 1 0 - FIR = 32 not recommended
0 1 1 - FIR = 64 not recommended
1 0 0 - FIR = 128
1 0 1 - FIR = 256
1 1 0 - FIR = 512
1 1 1 - FIR = 1024
0 0 0 - GAIN = 1 - Amplifier is bypassed
0 0 1 - GAIN = 3
0 1 0 - GAIN = 6
0 1 1 - GAIN = 12,5
1 0 0 - GAIN = 25
1 0 1 - GAIN = 50
1 1 0 - GAIN = 100
1 1 1 - GAIN = 100
M - Melexis reserved - Do not change
0 - Enable sensor test
1 - Disable sensor test
Note: The following bits/registers should not be altered (except with special tools – contact Melexis for tools
availability) in order to keep the factory calibration relevant: Ke [15..0] ; Config Register1 [13..11;7;3] ;
addresses 0x00F and 0x019.
