MPU ACCUMULATION OUTPUT VARIABLES
Accumulation values are accumulated from XFER cycle to XFER cycle (see Table 1-11). They are organized as
two 32-bit registers. The first register stores the decimal number displayed on the LCD. For example, if the LCD
shows “001.004”, the value in the first register is 1004. This register wraps around after the value 999999 is
reached. The second register holds fractions of the accumulated energy, with an LSB of
9.4045*10
-13
*VMAX*IMAX*In_8 Wh.
The MPU accumulation registers always hold positive values.
The CLI commands with two question marks, e.g.
)39??
should be used to read the variables.
