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.
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.
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.
001, 101, 110, 111: reserved.

001, 101,110,111: reserved.
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.
101, 110, 111: reserved. When set, the ADE7880 behaves like PGA1[2:0] = 000.
