IF NORMAL SCALING IS SELECTED
EQUATION 8:
Register Value = Source Value / Scale
IF REMAINDER SCALING IS SELECTED
EQUATION 9:
Register Value = Remainder of [Source Value/Scale] (commonly referred to as the modulus
function).
IF BIPOLAR CURRENT IS SELECTED
EQUATION 10:
Register Value = (2
IF BIPOLAR VOLTAGE IS SELECTED
EQUATION 11:
Register Value = (2
IF BIPOLAR POWER IS SELECTED
EQUATION 12:
Register Value = (2
IF UNIPOLAR OR NEGATIVE UNIPOLAR EQUATIONS ARE USED, Then the BIPOLAR equations above are
applicable with the note that,
FOR UNIPOLAR, if the result of the equation (10,11,or 12) is positive, then the register is filled with the value
calculated, else the reported value is 0
FOR NEGATIVE UNIPOLAR, If the result of the equation (10,11, or 12) is negative, then the register is filled with
the absolute value of the equation. If the calculated value is positive in sign, then the reported value is 0.
One should notice that if equations 5, 6, 7, 10, 11,or 12 are used, the SCALE entry shown in Figure 5-12?, refers
to the full scale value referenced in the equations. If equations 8 or 9 are used, the SCALE entry shown in Figure
8-2 refers to the Scale divisor denominator as referenced.
TPU2000 and 2000R User Definable Register Defaults
The TPU2000 and 2000R contains User Definable Register default mappings as shown in Table 5-11 below. It
should be noted that the register shall saturate at the maximum values computed and shown in Table 5-10 above.
The maximum saturation value can be computed to be 2N-1 where N is the register size in bits.
