Output
Address bit0. The address bus specifies either the row address or column
address. Also shared as boot-rom address bit0. This pin should be pull-
down.
Output
Address bit1. Also shared as boot-rom address bit1. Also used during
reset to latch in the strap value for Mini PCI sel; if set to a '1' implies Mini
PCI mode.
Output
Address bit2. Also shared as boot-rom address bit2. Also used during
reset to latch in the strap value for usbsel; if set to a '1' implies usb mode.
Output
Address bit3. Also shared as boot-rom address bit3. This pin should be
pull-down.
Output
Address bit4. Also shared as boot-rom address bit4. Also used during
reset to latch in the strap value for romcfg; if set to a '1' implies Mini PCI
configuration data should be downloaded from ROM.
Output
Address bit5. Also shared as boot-rom address bit5. Also used during
reset to latch in the strap value for test_rst_enb; if set to a '0' implies
normal operation mode.
Output
Address bit6. Also shared as boot-rom address bit6. Also used during
reset to latch in the strap value for freq_sel(0). Freq_sel(2:0) is used to
select the multiplication factor for the internal PLL (000=1x, and 111=8x).
Output
Address bit7. Also shared as boot-rom address bit7. Also used during
reset to latch in the strap value for freq_sel(1). Freq_sel(2:0) is used to
select the multiplication factor for the internal PLL (000=1x, and 111=8x).
Output
Address bit8. Also shared as boot-rom address bit8. Also used during
reset to latch in the strap value for freq_sel(2). Freq_sel(2:0) is used to
select the multiplication factor for the internal PLL (000=1x, and 111=8x).
Output
Address bit9. Also shared as boot-rom address bit9. Also used during
reset to latch in the strap value for sdram_delay(0). Sdram_delay(2:0) is
used to select the delay factor for the internal memory clock (000=0ns,
and 111=1.75ns with each .25ns increments).
