External clock/crystal oscillator pin
Notes: 1. VccQ-RTC must be supplied even if the realtime clock (RTC) is not used.
2. RTC in this LSI does not operate even if VccQ-RTC is turned on. The crystal oscillator
circuit for RTC operates with VccQ-RTC. The control circuit and the RTC counter
operate with Vcc (common to the internal circuit). Therefore, all power supplies other
than VccQ-RTC should always be turned on even if only RTC operates.
3. Vcc-PLL1/Vcc-PLL2 must be supplied even if the on-chip CPG is not used.
4. VccQ (3.3 V), Vcc (1.5 V), VssQ, and Vss must be connected to the system power
supply (for uninterrupted supply).
