PCI Reset
Pin Name: PCI_RST_N
Pin Number: 96
PCI_RST_N is an active low input that is used to set the internal registers to their initial state. PCI_RST_N is
typically the system power-on reset signal as distributed on the PCI bus.
PCI M66EN
Pin Name: PCI_M66EN
Pin Number: 152
This pin configures the PCI bus operating frequency. When low, the PCI bus operates from 0 to 33 MHz. When
high, the PCI bus operates from 33MHz to 66MHz.
Miscellaneous I/O
Flash Signals
Pin Name: FL_ADDR00 / CLASS_SEL
Pin Number: 49
When PCI_RST_N is deasserted, this pin is an output and represents flash memory address bit 0. During reset, it
is sampled to configure Mass Storage class or RAID mode in the PCI Class Code register. A high on this pin sets
Mass Storage class, a low sets RAID mode. The configuration state is latched internally when PCI_RST_N is
deasserted. This pad is internally pulled high to enable Mass Storage class if left unconnected.
Pin Name: FL_ADDR01 / BA5_EN
Pin Number: 50
When PCI_RST_N is deasserted, this pin is an output and represents flash memory address bit 1 During reset, it
is sampled to configure Base address register 5. A high on this pin enables base address register 5, a low
disables base address register 5. The configuration state is latched internally when PCI_RST_N is deasserted.
This pin is internally pulled high to enable Base address register 5 when left unconnected.
Pin Name: FL_ADDR[02-18]
Pin Numbers: 51, 54-57, 62-64, 66-69, 75-77, 79, 80
Flash Memory address bits; 19 total for 512K address space. Flash address pins 14 to 18 are used to select
internal test modes in conjunction with the TEST_MODE pin.
Pin Name: FL_DATA[0-7]
Pin Numbers: 85-87, 90-94
8-bit Flash memory data bus or GPIO pins
Pin Name: FL_RD_N
Pin Number: 52
Flash read enable signal, active low
Pin Name: FL_WR_N
Pin Number: 53
Flash write enable signal, active low
Pin Name: FL_CS_N
Pin Number: 81
Flash chip select signal, active low
Serial EEPROM Interface Signals
Pin Name: EEPROM_SDAT
Pin Number: 47
Serial Interface (I2C) data line
Pin Name: EEPROM_SCLK
Pin Number: 48
Serial Interface (I2C) clock
