SINGLE PHASE BIDIRECTIONAL POWER/ENERGY METERING IC WITH SERIAL INTERFACE

South African Micro Electronic Systems 

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.
