Angular Sensor for Position Control with
Side-Shaft Positioning Capability
1. Convert into binary: within a resolution of 12
bits, 50 deg is the binary number
001000111000 (49.92 deg).
2. Store the 8 MSB (00100011) of the zero
position into register 4:
command reg. address MSB
value
LSB
0010 0100 00100011
3. Read back the register 4
command reg. address MSB
value
LSB
0001 0100 00000000
If the programming was correct the MagAlpha
replies with the register 4 content:
Angle out
MSB
value
LSB
A(15:12)
A(11:8) 0 0 1 0 0 0 1 1
4. Then store the 4 LSB (1000) of the zero
position into the 4 LSB of register 5:
command reg. address MSB
value
LSB
0010 0101 00001000
5. Read back the register 5:
command reg. address MSB
value
LSB
0001 0101 00000000
The MagAlpha returns:
Angle out
MSB
value
LSB
A(15:12)
A(11:8) 0 0 0 0 1 0 0 0
6. Connect the VFLASH pin to 3.6 V
7. Flash register 4:
command reg. address MSB
value
LSB
0010 1001 00010000
8. Flash register 5:
command reg. address MSB
value
LSB
0010 1001 00100000
9. Disconnect the VFLASH pin from 3.6 V.
10. Turn the MagAlpha off and on, and read back
the registers 4 and 5 to verify that the flashing
was successfully accomplished (steps 3 & 5).
