Table 44. CFMODE Register (Address 0xE610)

Bit

Mnemonic

Default Value

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.

each phase identified by Bits[5:3] (TERMSEL2[x]) in the COMPMODE register.

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.
