An explanation of some of the above default mappings are offered as a guide to understanding the scaling
methodology implementation. Figure 5-31 illustrates the scaling procedure for remapped registers 40001 through
40032 Registers 257, 259, and 261 (as detailed in Table 5-11 above) contain the MMI reported current values to
be remapped and re-scaled to 12 bit Offset Bipolar Values.
