Notes: Supply power to all power pins. However, on the SH7751 in hardware standby mode,
supply power to RTC at the minimum.
Power must be supplied to VDD-PLL1/2 and VSS-PLL1/2 regardless of whether or not the
on-chip PLL circuits are used.
Power must be supplied to VDD-CPG and VSS-CPG regardless of whether or not the on-
chip crystal oscillation circuit is used.
Power must be supplied to VDD-RTC and VSS-RTC regardless of whether or not the on-
chip RTC is used.
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.
