Description
Connects the RESET pin of the ADE7953 to ADuM1401 Isolator U2. Use this configuration in normal operation when
software management of the RESET pin is done via the interface board and the ADE7953 evaluation software.
Disconnects the RESET pin of the ADE7953 from ADuM1401 Isolator U2. Use this configuration when software
management of the RESET pin is not desired.
