Notes: 1. Regardless of whether PLL or RTC is used, connect VCC(PLL), VCC(RTC) to VCC, and
VSS(PLL), VSS(RTC) to VSS.
2. Current condition is VIH min = VCC â 0.5 V, VIL max = 0.5 V, and all output pins
unloaded.

17.3 AC Characteristics
Input for the LSI should, as a rule, be clock synchronous. Keep to the setup and hold times for
each input signal unless otherwise directed.
