2.4 Onboard Memory
2.4.1 Configuration EEPROM
The Configuration EEPROM is a 1 MBit (128 kB, 64 x 16 organization) EEPROM for storing
board control relevant information for the operation of the Gigabit Ethernet controller as well as
the PCI / PCI-X interfacing to a host CPU or System Master.
2.4.2 Flash Memory
The PMC240 has provision for adding up to 512 kB of optional Flash memory for additional
data storage. This memory is controlled by the Gigabit Ethernet device but is accessible from
a host CPU or System Master. As such this memory can be used for a variety of functionality
including the ability to boot a host CPU or System Master from LAN.
2.5 Monitor and Control (M/C)
Monitor and Control functions are divided essentially into Pre-operation and Operation. Pre-op-
eration M/C deals with board configuration and system requirements. Operation M/C covers di-
rect operator interfaces.
2.5.1 Pre-Operation M/C
Pre-operation M/C is a direct function of the application and the system requirements. These
requirements dictate the module configuration as well as the overall system integration. Overall
system integration and compliance with its requirements is beyond the scope of this manual.
2.5.2 Operation M/C
Operation M/C is a function of the PMC240 driver software and the application. Direct interac-
tion by the operator is limited to the functionality provided by the LED’s assigned to the respec-
tive Ethernet channels. These LED’s can be used to determine the basic operational status of
a channel and if data is being transferred.
