User Options
The PCI-60A uses a switch for controlling the EEPROM configuration. Settings are
described below.
Switch SW1
Position 1
EESEL
Selects the size of the EEPROM. OFF selects the 1K 93CS46 and ON selects the 2K
93CS56 part. Leave in the ON position (factory default).
Position 2
SHORT
The SHORT switch is used by the PCI 9080 to determine the size of the EEPROM. When
in the ON position, the PCI 9080 will only read the first five configuration registers and will
not request any space for the PCI-60A IndustryPacks. When in the OFF position (factory
default), all configuration registers will be read.
Position 3
EEPROM Data Out
This switch connects the EEPROM Data Out pin to the PCI 9080 device. When in the
OFF position, the PCI 9080 will power up with its factory defaults. It will not request any
space for the IndustryPacks during the PCI BIOS configuration process. When in the ON
position (factory default), the PCI 9080 device will read the EEPROM after power up and
use that information during the PCI BIOS configuration.
Position 4
EEPROM PE
The EEPROM PE switch and the EEPROM PRE switch are used to enable programming
of the EEPROM. When in the OFF position, the EEPROM Program Enable (PE) pin is
pulled to VCC by a 4.7K Ohm resistor. This allows programming of the EEPROM. When
in the ON position (factory default), the PE pin is tied to GND. This prevents any
programming of the EEPROM.
Position 5
EEPROM PRE
The EEPROM PRE switch and the EEPROM PE switch are used to enable programming
of the EEPROM. When in the OFF position, the EEPROM Protect Register Enable (PRE)
pin is pulled to VCC by a 4.7K Ohm resistor. This allows programming of the EEPROM
protect register. When in the ON position (factory default), the PRE switch connects the
pin to GND. This enables programming of the EEPROM data area and prevents
programming of the protect register.
