saving coefficients and some input registers into flash memory. It also allows issuing calibration
commands.
Save to Flash Command
Use the ACC command to save to flash the calibration coefficients and system defaults contained in the
some of the input registers. Upon reset or power-on, the values stored in flash will become new system
defaults.
The following table describes the ACC command bits:
operations, and Line Lock mode etc.
3.8 Command Register
The Command Register is located at address 0x00. Use this register to perform specific tasks such as
General Settings (Command 000)
The general settings command allows the user to enable functions such as UART auto reporting, relay

“General settings” command.
Not Used
Stop temperature update: 1=stop; 0=update.
This bit prevents the firmware from overwriting the TempC (temperature result)
register. This is necessary when supplying a known temperature for calibration.
Stop Frequency update 1=stop; 0=update.
This bit stops the update of Freq used by the sine/cosine generator for
fundamental and harmonic measurements. It is the unscaled value of
Frequency with 8 integer and 16 fraction bits. The user can set the fundamental
frequency when FREQ is set.
Line Lock 1= lock to line cycle; 0= independent.
This bit selects the accumulation interval (computation cycle) mode. If not
locked the computation is executed over a fixed number of samples (high rate)
contained in the Accum register. If locked, the computation is executed over a
number of samples accumulation interval.
Enable Gain/Temperature compensation 1=enable; 0=disable.
This bit allows the firmware to modify the system gain based on measured
temperature.
Enable Auto Reporting 1=enable; 0=disable.
This bit enables auto reporting mode on UART. The user or host can also set or
clear this command bit, enabling or disabling auto reporting.
Enable Autonomous Relay operation 1=enable; 0=disable/normal mode.
This bit enables autonomous relay operation. The user or host can also set or
clear this command bit, enabling or disabling autonomous operation.
Not used
“Access” Command.
2: Save Calibration to flash.
Not used.
Line Lock Bit.
