Description
000: the CF1 frequency is proportional to the sum of total active powers on each phase
identified by Bits[2:0] (TERMSEL1[x]) in the COMPMODE register.
001: the CF1 frequency is proportional to the sum of total reactive powers on each phase
identified by Bits[2:0] (TERMSEL1[x]) in the COMPMODE register. This condition does not
have any consequence for the ADE7854 .
010: the CF1 frequency is proportional to the sum of apparent powers on each phase
identified by Bits[2:0] (TERMSEL1[x]) in the COMPMODE register.
011: the CF1 frequency is proportional to the sum of fundamental active powers on each
phase identified by Bits[2:0] (TERMSEL1[x]) in the COMPMODE register. This condition does
not have any consequence for the ADE7854 , ADE7858 , and ADE7868 .
100: the CF1 frequency is proportional to the sum of fundamental reactive powers on each
phase identified by Bits[2:0] (TERMSEL1[x]) in the COMPMODE register. This condition does
not have any consequence for the ADE7854 , ADE7858 , and ADE7868 .
101, 110, 111: reserved. When set, the CF1 signal is not generated.

identified by Bits[5:3] (TERMSEL2[x]) in the COMPMODE register.
001: the CF2 frequency is proportional to the sum of total reactive powers on each phase
identified by Bits[5:3] (TERMSEL2[x]) in the COMPMODE register. This condition does not
have any consequence for the ADE7854 .
010: the CF2 frequency is proportional to the sum of apparent powers on each phase
identified by Bits[5:3] (TERMSEL2[x]) in the COMPMODE register.
011: the CF2 frequency is proportional to the sum of fundamental active powers on each
phase identified by Bits[5:3] (TERMSEL2[x]) in the COMPMODE register. This condition does
not have any consequence for the ADE7854 , ADE7858 , and ADE7868 .
100: the CF2 frequency is proportional to the sum of fundamental reactive powers on each
phase identified by Bits[5:3] (TERMSEL2[x]) in the COMPMODE register. This condition does
not have any consequence for the ADE7854 , ADE7858 , and ADE7868 .
101,110,111: reserved. When set, the CF2 signal is not generated.

CF3SEL[2:0]
010
000: the CF3 frequency is proportional to the sum of total active powers on each phase
identified by Bits[8:6] (TERMSEL3[x]) in the COMPMODE register.
001: the CF3 frequency is proportional to the sum of total reactive powers on each phase
identified by Bits[8:6] (TERMSEL3[x]) in the COMPMODE register. This condition does not
have any consequence for the ADE7854 .
010: the CF3 frequency is proportional to the sum of apparent powers on each phase
identified by Bits[8:6] (TERMSEL3[x]) in the COMPMODE register.
011: CF3 frequency is proportional to the sum of fundamental active powers on each phase
identified by Bits[8:6] (TERMSEL3[x]) in the COMPMODE register. This condition does not
have any consequence for the ADE7854 , ADE7858 , and ADE7868 .
100: CF3 frequency is proportional to the sum of fundamental reactive powers on each
phase identified by Bits[8:6] (TERMSEL3[x]) in the COMPMODE register. This condition does
not have any consequence for the ADE7854 , ADE7858 , and ADE7868 .
101,110,111: reserved. When set, the CF3 signal is not generated.

When this bit is set to 1, the CF1 output is disabled. The respective digital to frequency
converter remains enabled even if CF1DIS = 1.
When this bit is set to 0, the CF1 output is enabled.
