Chapter 1: Hardware Description

These devices keep their programming during power off. So the EPLD should normally be already programmed and the normal user should not be aware of its programming.

The EPLDs are in a daisy-chain configuration, which enables all of them to be programmed at once. They can be programmed in-situ by the PCI host, using some PowerSpan interrupts as I/O pins. A jumper must be placed on board location JP1 to enable the programming (when present, this jumper sets the ISP signal –ISPEN to its active state 0).

Serial EEPROM Connected to the PowerSpan

An I²C serial EEPROM is connected to the PowerSpan. It is used to store some PowerSpan register initialization values and the PCI Vital Product Data (VPD). Other Interphase- specific data is stored there, and there is still some room for other custom data. Table 1-22shows the memory mapping for the EEPROM.

Details about the PowerSpan register initial load are described on Table 2-1 on page 60. Additional information concerning Interphase-specific Production Data and Boot Monitor parameters are provided in the 4538 Built-In Self Test and Monitor Manual. The VPD and/or Custom Data is available space, for later use)

Board Equipment Register

The “Board Equipment Register” is a 32-bit word that allows the software to precisely determine the board equipment. The first three bytes are common to several Interphase Boards, so many field values are not possible on the 4538. For instance the 4538 does not have Monarch capability, so the Monarch bit will always be set to 0.
