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 – 0.5 V, VIL max = 0.5 V, and all output pins

unloaded.

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.
