ADE7854/ADE7858/ADE7868/ADE7878
Second, Bits[2:0] (CF1SEL[2:0]), Bits[5:3] (CF2SEL[2:0]), and
Bits[8:6] (CF3SEL[2:0]) in the CFMODE register decide what
type of power is used at the inputs of the CF1, CF2, and CF3
converters, respectively. Table 22 shows the values that CFxSEL
can have: total active, total reactive (available in the ADE7858,
ADE7868, and ADE7878 only), apparent, fundamental active
(available in the ADE7878 only), or fundamental reactive
(available in the ADE7878 only) powers.
