HOLD pin is pulled down in the LSI, but normally pulled up to VDD. RESET pin is pulled up to VDD.
Setting POWER SW to ON, V2 is supplied to VDD pin, and also to HOLD pin. Then calculator operates normally. Setting POWER SW from ON to OFF, V1 is supplied to VDD pin and VSS is supplied to HOLD pin. Under this connection, TAX RATE is held. Setting POWER SW to ON, V2 is supplied to VDD pin, and also to HOLD pin. Then calculator operates normally with TAX RATE to be held.
Note 12: V1 (battery) should be supplied to the circuit after V2 (DC) supply, because of prevention from exhaustion of battery and abnormal operation.
