Command Register
The Command Register is located at address 0x00. Use this register to perform specific tasks such as
saving coefficients and nonvolatile register defaults into flash memory. It also allows initiation of
integrated calibration routines.

Normal Operation
The general settings command allows the user to enable functions such as UART auto reporting, relay
operations, and Line Lock mode etc.

Description
“General settings” command used during normal operation.
Line Lock 1 = lock to line cycle; 0 = independent.

Calibration Command
The Calibration Command starts the calibration process for the selected inputs. It is assumed that
appropriate input signals are applied. When the calibration process completes, bits 23:16 are cleared
along with bits associated with channels that calibrated successfully. When calibrating gain, any channels
that failed will have their corresponding bit left set. When calibrating offset, the bit corresponding to the
selected channels will remain set.
