Section 3
Serial EEPROM Reset and Initialization
Table 3-1. Serial EEPROM Guidelines
3.3.1
The serial EEPROM load sequence, listed in Table
3-2, uses the following abbreviations:
• MSW = Most Significant Word bits [31:16]
• LSW = Least Significant Word bits [15:0]
3.3.1.1
The registers listed in Table 3-2 are loaded from the
serial EEPROM after a PCI reset is de-asserted. The
serial EEPROM is organized in words (16 bit). The
PCI 9030 first loads the Most Significant Word bits
(MSW[31:16]), starting from the most significant bit
([31]). The PCI 9030 then loads the Least Significant
Word bits (LSW[15:0]), starting again from the most
significant bit ([15]). Therefore, the PCI 9030 loads the
Device ID, Vendor ID, Class Code, and so forth.
The serial EEPROM values can be programmed using
a serial EEPROM programmer or PLXMon™ software.
The values can be programmed using the PCI 9030
VPD function (refer to Section 9) or through the Serial
EEPROM Control register (CNTRL).
The CNTRL register allows programming of the serial
EEPROM, one bit at a time. To read back the value
from the serial EEPROM, the Vital Product Data (VPD)
function can be utilized. With full utilization of VPD, the
designer can perform reads and writes from/to the
serial EEPROM, 32 bits at a time. Values should be
programmed in the order listed in Table 3-2. The 68,
16-bit words listed in the table are stored sequentially
in the serial EEPROM.

3.3.1.2
The PCI 9030 is designed to use serial EEPROMs
with a three-wire serial interface, powered at 3.3V, and
that support 250 kHz clocking and sequential reads.
