APT Enabled = 1
APT Disabled = 0
Bit 1 – APT Polarity:
1 = high value 20 mA
0 = high value 4 mA
Bit 2 – ATT (Analog Torque Transmitter)
ATT Enabled =1
ATT Disabled = 0
Bit 3 – ATT Polarity:
1 = high value 20 mA
0 = high value 4 mA
Bit 4 – DDC Offset:
1 = 4 mA
0 = 0 mA
Bits 5-8 – Not Used
Bits 9-10 – Scaling:
0 = 0-100
1 = 0-255
2 = 0-4,095
