				VDO = VCC / 2
*1	: Conditions ; fosc = 12.8 MHz, Ta = +25 °C, SW = “0” in locking state.
*2	: VCCIF = VCCRF = 3.0 V, fosc = 12.8 MHz, Ta = +25 °C, in power saving mode.
	PSIF = PSRF = GND
	VIH = VCC, VIL = GND (at CLK, Data, LE)
*3	: AC coupling. 1000 pF capacitor is connected under the condition of Min operating frequency.
*4	: The symbol “–” (minus) means the direction of current flow.
*5	: VCC = 3.0 V, Ta = +25 °C (I3 − I4) / [ (I3 + I4) / 2] ⋅ 100 (%)
*6	: VCC = 3.0 V, Ta = +25 °C [ (I2 − I1) / 2] / [ (I1 + I2) / 2] ⋅ 100 (%)				(Applied to both lDOL and lDOH)
*7	: VCC = 3.0 V, [IDO (+85 °C) − IDO (–40°C) / 2] / [IDO (+85 °C) + IDO (–40°C) / 2] ⋅ 100 (%) (Applied to both IDOL and IDOH)
*8	: When Charge pump current is measured, set LDS = “0” , T1 = “0” and T2 = “1”.
