*1 : Conditions ; fosc = 13 MHz, Ta = +25 °C in locking state.
*2 : VCCIF = VpIF = VCCRF = VpRF = 3.0 V, fosc = 13 MHz, Ta = +25 °C, in power saving mode.
*3 : AC coupling. 1000 pF capacitor is connected.
*4 : The symbol “–” (minus) means direction of current flow.
*5 : VCC = Vp = 3.0 V, Ta = +25 °C (||I3| − |I4||) / [ (|I3| + |I4|) / 2] × 100 (%)
