Notes: 1. Except in hardware standby mode, supply power to all power pins. In hardware standby
mode, supply power to RTC as a minimum.
2. Power must be supplied to VDD-PLL1/2 and VSS-PLL1/2 regardless of whether or not
the on-chip PLL circuits are used.
3. Power must be supplied to VDD-CPG and VSS-CPG regardless of whether or not the
on-chip crystal resonator is used.
4. Power must be supplied to VDD-RTC and VSS-RTC regardless of whether or not the
on-chip RTC is used.
5. For the handling of the PCI bus pins in PCI-disabled mode, see table D.4 in appendix
D.
*1 I/O attribute is I/O when used as a port.
*2 May be connected to V_SSQ.
