*1
Output when area 2 DRAM is used.
*2
Output when area 5 PCMCIA is used.
*3
Output when area 6 PCMCIA is used.
*4
Depends on refresh and DMAC operations.
*5
Z (I) or O (refresh), depending on register setting (BCR1.HIZCNT).
*6
Depends on refresh operation.
*7
Z (I) or H (state held), depending on register setting (BCR1.HIZMEM).
*8
Z or O, depending on register setting (STBCR.PHZ).
*9
Output when refreshing is set.
*10 Z or O, depending on register setting (FRQCR.CKOEN).
*11 Z or O, depending on register setting (STBCR.STHZ).
*12 Pullup, depending on register setting (PCICR.PCIPUP).
*13 Pullup, depending on register setting (STBCR.PPU).
*14 Pullup, depending on register setting (BCR1.IPUP).
*15 Pullup, depending on register setting (BCR1.OPUP).
*16 Pullup, depending on register setting (BCR1.DPUP).
*17 Pullup, depending on register setting (BCR2.PORTEN).
*18 Pullup, depending on register setting (PCIPCTR.PB2PUP to PCIPCTR.PB4PUP).
*19 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 the
SH-4.
