identified by Bits[2:0] (TERMSEL1[x]) in the COMPMODE register.

010: CF1 frequency is proportional to the sum of the apparent powers on each phase

identified by Bits[2:0] (TERMSEL1[x]) in the COMPMODE register.

CF1DIS

0: CF1 output is enabled.

1: CF1 output is disabled. The energy-to-frequency converter remains enabled.

CF2DIS

0: CF2 output is enabled.

1: CF2 output is disabled. The energy-to-frequency converter remains enabled.

CF3DIS

0: CF3 output is enabled.

CF1LATCH

0: no latching of energy registers occurs when a CF1 pulse is generated.

1: the contents of the corresponding energy registers are latched when a CF1 pulse

is generated. See the Synchronizing Energy Registers with the CFx Outputs section.

CF2LATCH

0: no latching of energy registers occurs when a CF2 pulse is generated.

1: the contents of the corresponding energy registers are latched when a CF2 pulse is

generated. See the Synchronizing Energy Registers with the CFx Outputs section.

CF3LATCH

0: no latching of energy registers occurs when a CF3 pulse is generated.

1: the contents of the corresponding energy registers are latched when a CF3 pulse is

generated. See the Synchronizing Energy Registers with the CFx Outputs section.

Reserved
