Reserved
Setting this bit to 1 starts the SRAM BIST engine. R/W
This bit is set to 1 when the SRAM BIST completes each section. RO
This bit is set to 1 if the SRAM BIST detects a failure in RX Status
FIFO SRAM. This bit is cleared only by resetting the BIST. RO
This bit is set to 1 if the SRAM BIST detects a failure in RX Data FIFO
SRAM. This bit is cleared only by resetting the BIST. RO

This bit is set to 1 if the SRAM BIST detects a failure in TX Data FIFO
SRAM. This bit is cleared only by resetting the BIST. RO
This bit is set to 1 if the SRAM BIST detects a failure in the hash filter
SRAM. This bit is cleared only by resetting the BIST. RO
This bit is set to 1 if the SRAM BIST detects a failure in the RX filter
SRAM. This bit is cleared only by resetting the BIST. RO
This bit is set to a 1 to manually initiate a load of configuration
information from EEPROM. A 1 is returned while the configuration
load from EEPROM is active. R/W
This bit is set to a 1 to initiate EEPROM BIST, which verifies the
EEPROM data and checksum without reloading configuration values
to the device. A 1 is returned while the EEPROM BIST is active. R/W
This bit is set to a 1 upon completion of the EEPROM BIST
(EEBIST_EN returns 0) if the BIST logic encountered an invalid
checksum. RO
4.2.6 Interrupt Status Register
This register indicates the source of an interrupt when the INTA pin goes active. Enabling the corresponding bits in the
Interrupt Mask Register (IMR) allows bits in this register to produce an interrupt. When an interrupt is active, one or more
bits in this register are set to a 1. The Interrupt Status Register reflects all current pending interrupts, regardless of the
state of the corresponding mask bit in the IMR. Reading the ISR clears all interrupts. Writing to the ISR has no effect.

General Description
DP83820 is a single-chip 10/100/1000 Mb/s Ethernet Controller for the PCI bus. It is targeted at high
performance adapter cards and mother boards. The DP83820 fully implements the V2.2 66 MHz, 64-bit PCI bus interface for host communications with power management support. Packet descriptors and data are transferred via bus-mastering, reducing the burden on the host CPU. The DP83820 can support full duplex 10/100/1000 Mb/s transmission and reception.

Features
— IEEE 802.3 Compliant, 66/33 Mhz, 64/32-bit PCI V2.2 MAC/BIU supports data rates from 1 Mb/s to 1000 Mb/s. This allows support for traditional 10 Mb/s Ethernet, 100 Mb/s Fast Ethernet, as well as 1000 Mb/s Gigabit Ethernet.
— Flexible, programmable Bus master - burst sizes of up to 256 dwords (1024 bytes)
— BIU compliant with PC 97 and PC 98 Hardware Design Guides, PC 99 Hardware Design Guide draft, ACPI v1.0, PCI Power Management Specification v1, OnNow Device Class Power Management Reference Specification - Network Device Class v1.0a
— Wake on LAN (WOL) support compliant with PC98, PC99, and OnNow, including directed packets, Magic Packet with SecureOn, ARP packets, pattern match packets, and Phy status change
— GMII/MII provides IEEE 802.3 standard interface to support 10/100/1000 Mb/s physical layer devices
— Ten-Bit Interface (TBI) for support of 1000BASE-X
— Virtual LAN (VLAN) and long frame support. VLAN tag insertion support for transmit packets. VLAN tag detection and removal for receive packets
— 802.3x Full duplex flow control, including automatic transmission of Pause frames based on Rx FIFO thresholds
— IPv.4 checksum task off-loading. Supports checksum generation and verification of IP, TCP, and UDP headers
— 802.1D and 802.1Q priority queueing support. Supports multiple priority queues in both transmit and receive directions.
— Extremely flexible Rx packet filtration including: single address perfect filter with MSb masking, broadcast, 2,048 entry multicast/unicast hash table, deep packet pattern matching for up to 4 unique patterns.
— Statistics gathered for support of RFC 1213 (MIB II), RFC 1398 (Ether-like MIB), IEEE 802.3 LME, reducing CPU overhead for management.
— Internal 8 KB Transmit and 32 KB Receive data FIFOs
— Supports Jumbo packets
— Serial EEPROM port with auto-load of configuration data from EEPROM at power-on
— Flash/PROM interface for remote boot support
— Full Duplex support for 10/100/1000 Mb/s data rates
— 208-pin PQFP package
— Low power CMOS design
— 3.3V powered I/Os with 5V tolerant inputs
— JTAG Boundary Scan supported
