PRODUCTION DATA.
The VIN_UV_FAULT_LIMIT command sets the value of the input voltage that causes an Input Under voltage Fault. This fault is masked until the input exceeds the value set by the VIN_ON command for the first time, and the unit has been enabled. VIN_UV_FAULT_LIMIT is a linear format command, and must be accessed through Read Word/Write Word transactions. The VIN_UV_FAULT_LIMIT command is shared between Channel A and Channel B. All transactions to this command will affect both channels regardless of the PAGE command.
