D. Pin Functions
K:
Output state held
IZ/IOZ: Response to access from PCI
PZ: Pulled up with a built-in pull-up resistance
PI: Input pulled up with a built-in pull-up resistance
ODK: Open-drain output state held
Notes: 1. Output when area 5 PCMCIA is used.
2. Output when area 6 PCMCIA is used.
3. Z (I) or O (refresh), depending on register setting (BCR1.HIZCNT).
4. Depends on refresh operation.
5. Z (I) or H (state held), depending on register setting (BCR1.HIZMEM).
6. Z or O, depending on register setting (STBCR.PHZ).
7. Output when refreshing is set.
8. Z or O, depending on register setting (FRQCR.CKOEN).
9. Z or O, depending on register setting (STBCR.STHZ).
10. Pullup, depending on register setting (PCICR.PCIPUP).
11. Pullup, depending on register setting (STBCR.PPU).
12. Pullup, depending on register setting (BCR1.IPUP).
13. Pullup, depending on register setting (BCR1.OPUP).
14 Pullup, depending on register setting (BCR1.DPUP).
15. Pullup, depending on register setting (BCR2.PORTEN).
16. Pullup, depending on register setting (PCIPCTR.PB2PUP to PCIPCTR.PB4PUP).
17. Pullup by on-chip pullup resistor. Note that this cannot be used for pullup of the mode
pin during a power-on reset. Pullup or pulldown should be performed externally to this
LSI.
D.2 Handling of Unused Pins
• When RTC is not used
⎯ EXTAL2: Pull up to 3.3 V
⎯ XTAL2: Leave unconnected
⎯ VDD-RTC: Power supply
⎯ VSS-RTC: Power supply
• When PLL1 is not used
⎯ VDD-PLL1: Power supply
⎯ VSS-PLL1: Power supply
