FAC
Determines if anti-creep is enabled for pulse output E3.
0 = Disable anti-creep (default)
1 = Enabled anti-creep
EAC
Determines if anti-creep is enabled for pulse output E1 and/or E2.
0 = Disable anti-creep (default)
1 = Enabled anti-creep
STOP
Terminates the auto-boot sequence.
0 = Normal (default)
1 = Stop sequence
MECH
Mechanical Counter Format, E1 or E2 becomes active low pulses with an output frequency pro-
portional to the active power
0 = Normal (default) or Stepper Motor Format
1 = Mechanical Counter Format, also ALT = 0
INTOD
Converts INT output pin to an open drain output.
0 = Normal (default)
1 = Open drain
NOCPU
Saves power by disabling the CPUCLK pin.
0 = Normal (default)
1 = Disables CPUCLK
NOOSC
Saves power by disabling the crystal oscillator.
0 = Normal (default)
1 = Oscillator circuit disabled
STEP
Stepper Motor Format, E1 and E2 becomes active low pulses with an output frequency propor-
tional to the active power
0 = Normal Format (default)
1 = Stepper Motor Format, also MECH = 0 and ALT = 0

Default = 0x2F02C3 = 23.5073471
Sets the temperature channel gain. Temperature gain (TGain) is utilized to convert from one temperature scale to an-
other. The Celsius scale (oC) is the default. Values are represented in unsigned notation and in the range of
0 ≤ TGain < 128, with the binary point to the right of the seventh MSB.
