GD82559E R — Networkin g Silicon 14 Datasheet 4.2 PCI Interface 4.2. 1 825 59ER B us O p erations After configuration, the 82559ER is ready f or normal oper ation. As a Fast Ethernet contro ller , the role of the 82559ER is to access transmitted data or deposit received data.
Datashee t 15 Netw orkin g Silicon — G D82559ER The figures below show CSR zero wait-state I/O read and write cycles. In the case of accessing the Control/Status R e gi sters, the CPU is the initiator an d th e 82559ER is the target of the transaction.
GD82559E R — Networkin g Silicon 16 Datasheet controls the TRDY# signal and asserts it from the data access. The 82559 ER allows the CPU to issue only one I/O write cycle to the Control/Status Registers, generating a disconnect by asserting the STOP# signal.
Datashee t 17 Netw orkin g Silicon — G D82559ER Write Accesses: The CPU, as the initiator, drives the address lines AD[31:0], the command and byte enable lines C/BE# [3:0] an d the control lines IRD Y# and FRAME# . It also prov ides the 82559ER with valid d ata immediately after asserting IRDY# .
GD82559E R — Networkin g Silicon 18 Datasheet Note: The 82559ER is considered the target in the abo ve diagram; thus, TRDY# is not asserted. 4.2.1.1.4 Error Handlin g Data Parity Err ors: The 82559ER checks for data parity errors while it is the target of the transaction.
Datashee t 19 Netw orkin g Silicon — G D82559ER 8 depict memory read and write burst cycles. For bus master cy cles, the 82559ER is the initiator and the host m ain memory (or the PCI host b ridge, depending o n the configuration o f the system) is the target.
GD82559E R — Networkin g Silicon 20 Datasheet Byte Count value indicates the maximum number of transmit DMA PCI cycles that will be completed after an 82559ER internal arbitration. (Details on the Configure command are described in t he S oftwar e Developer ’ s Man ual .
Datashee t 21 Netw orkin g Silicon — G D82559ER 1. Minimum transfer of o ne cache line 2. Active byte enable bits (or BE#[ 3:0] are all low) during MWI access 3. The 82559ER may cross the cache line bound ary only if it intend s to transfer the next cache line too.
GD82559E R — Networkin g Silicon 22 Datasheet • This feature is not recommended for use in non-cache line oriented systems since it may cause shorter burs ts and lo wer perfor mance. • This feature should be used only when the CLS register in PCI Configuration spac e is set to 8 or 16 Dwords.
