The Proposal of Outer Circuit for Tax Rate Holding with Back-Up Battery.
Note 8: V1 = 3 V: Battery supply
V2 = 5 V: DC supply
HOLD
pin is pulled up in the LSI.
RESET
pin is pulled up to VDD.
(1)
Setting HOLD SW to OFF, the calculator operates normally under V2 power supply.
(2)
Setting HOLD SW to ON, the calculator will be in HOLD mode with TAX RATE that has already held,
under V2 power supply.
(3)
TAX RATE that has already held is still held under V1 power supply, even if there is no V2 power
supply (no DC power supply).
Note 9: V1 (battery) should be supplied to the circuit after V2 (DC) supply, because of prevention from
exhaustion of battery and abnormal operation.
