4.5.2
During initialization, the CS5463 is configured to measure the fundamental frequency automatically – the
AFC bit of the Mode register is set by the MCU. The Define Fundamental Frequency selection box en-
ables the user to disable the automatic frequency calculation function and define the specific line frequen-
cy by changing the Epsilon register value..
4.5.3
The power measurement period or register refreshing rate depends on the CS5463 sample rate and the
configuration of the CS5463 CycleCount (N) register. By default, N is 4000 and the measurement period
is 1 second. The Measurement Period selection box is used to change the CS5463 CycleCount register
value (N) and therefore, change the measurement period.
