Appendix E Pin Functions
SH7750, SH7750S, SH7750R Group
19. Pulled up or not pulled up, depending on register setting (BCR1.DPUP) (SH7750R
only).
20. Z when CKIO2ENB = 1
21. BGA Package only.
22. Depends on Emulator operations.
E.2 Handling of Unused Pins
• When RTC is not used
⎯ EXTAL2: Pull up to 3.3 V
⎯ XTAL2: Leave unconnected
⎯ VDD-RTC: Power supply (3.3 V)
⎯ VSS-RTC: Power supply (0 V)
• When PLL1 is not used
⎯ VDD-PLL1: Power supply (3.3 V)
⎯ VSS-PLL1: Power supply (0 V)
• When PLL2 is not used
⎯ VDD-PLL2: Power supply (3.3 V)
⎯ VSS-PLL2: Power supply (0 V)
• When on-chip crystal oscillator is not used
⎯ XTAL: Leave unconnected
⎯ VDD-CPG: Power supply (3.3 V)
⎯ VSS-CPG: Power supply (0 V)
Note: To prevent unwanted effects on other pins when using external pull-up or pull-down
resistors, use independent pull-up or pull-down resistors for individual pins.
