SA9603C Datasheet, PDF (8/18 Pages) Sames – SINGLE PHASE BIDIRECTIONAL POWER/ENERGY METERING IC WITH SERIAL INTERFACE

SA9603C
Dump register values: The content of the individual registers are transmitted
sequentially, at the 'Dump' command. Transmission of the first register value will
start with the completion of the current measurement cycle (Maximum 8 mains
cycles). The sequence of the registers is always as follows: Mains voltage, mains
frequency, reactive energy register followed by the active energy register value. By
specifying the register in the DUMP command, register values are transmitted
starting with the specified register and stopping with the active energy register.
