CF2SEL[1:0]
Bit
Default
Value
Description
01
Configuration bits for CF2 output
CF2SEL[1:0] Source
00
CF2 frequency is proportional to active power
01
CF2 frequency is proportional to reactive power
1x
CF2 frequency is proportional to apparent power or
IRMS
Configuration bits for CF1 output
CF1SEL[1:0] Source
00
CF1 frequency is proportional to active power
01
CF1 frequency is proportional to reactive power
1x
CF1 frequency is proportional to apparent power or
IRMS
Configuration bits for apparent power or IRMS for CF1 and CF2 outputs
0
If CF1SEL[1:0]=1x, CF1 is proportional to VA
If CF2SEL[1:0]=1x, CF2 is proportional to VA
1
If CF1SEL[1:0]=1x, CF1 is proportional to IRMS
If CF2SEL[1:0]=1x, CF2 is proportional to IRMS
Note that CF1 cannot be proportional to VA if CF2 is proportional to IRMS
and vice versa
Logic one enables update of RMS values synchronously to voltage ZX

PER_FREQ register (0Ah)
0
PER_FREQ register holds a period measurement
1
PER_FREQ register holds a frequency measurement
