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 ADE7854/ADE7858/ADE7868/ADE7878 behaves like
CF1SEL[2:0] = 000.
000: the CF2 frequency is proportional to the sum of total active powers on each phase
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 ADE7854/ADE7858/ADE7868/ADE7878 behaves like
CF2SEL[2:0] = 000.
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.

101,110,111: reserved. When set, the ADE7854/ADE7858/ADE7868/ADE7878 behaves like
CF3SEL[2:0] = 000.
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.
When this bit is set to 1, the CF2 output is disabled. The respective digital to frequency
converter remains enabled even if CF2DIS = 1.
When this bit is set to 0, the CF2 output is enabled.
When this bit is set to 1, the CF3 output is disabled. The respective digital to frequency
converter remains enabled even if CF3DIS = 1.
When this bit is set to 0, the CF3 output is enabled.
