1. MUX_DIV[3:0] must be set to 0 while writing the other RAM locations in this table.
2. IN is the optional Neutral Current.
Maxim updates the CE code periodically. Contact your local Maxim representative to obtain the
latest CE code and the associated settings.
Using settings for the I/O RAM Mnemonics listed in Table 1 and Table 2 that do not match
those required by the corresponding CE code being used may result in undesirable side
effects and must not be selected by the MPU. Consult your local Maxim representative to
obtain the correct CE code and AFE / MUX settings corresponding to the application.
For a poly-phase configuration with neutral current sensing using shunt resistor current sensors and the
71M6xx3 isolated sensors, as shown in Figure 2 , the IADC0-IADC1 input must be configured as a
differential input, to be connected to a local shunt (see Figure 26 for the shunt connection details). The
local shunt connected to the IADC0-IADC1 input is used to sense the Neutral current. The voltage
sensors (VADC8, VADC9 and VADC10) are also directly connected to the 71M6545/H (see Figure 23 for
the connection details) and are also routed though the multiplexer, as seen in Figure 2 . Meanwhile, the
