25 / 89 page DM9103 3-port switch with PCI Interface Preliminary datasheet 25 DM9103-DS-P02 September 26, 2007 6.2.1 System Control Register (CR0) Bit Name Default Description 31:24 Reserved DEH,RO Reserved 25:22 Reserved 00,RO Reserved 21 MRM 0,RW Memory Read Multiple When set, the DM9103 will use memory read multiple command (C/BE3~0 1100) when it initialize the memory read burst transaction as a master device When reset, it will use memory read command (C/BE3 ~ 0 = 0110) for the same master operation 20 Reserved 0,RW Reserved 19:1 Reserved 0,RO Reserved 0 SR 0,RW Software Reset When set, the DM9103 will make a internal reset cycle. All consequent action to DM9103 should wait at least 32 PCI clock cycles for its self-cleared. 6.2.2 Transmit Descriptor Poll Demand (CR1) Bit Name Default Description 31:0 TDP FFFFFFFFH ,WO Transmit Descriptor Polling Command Writing any value to this port will force DM9103 to poll the transmit descriptor. If the acting descriptor is not available, transmit process will return to suspend state. If the descriptor shows buffer available, transmit process will begin the data transfer. 6.2.3 Receive Descriptor Poll Demand (CR2) Bit Name Default Description 31:0 RDP FFFFFFFFH ,WO Receive Descriptor Polling Command Writing any value to this port will force DM9103 to poll the receive descriptor. If the acting descriptor is not available, receive process will return to suspend state. If the descriptor shows buffer available, receive process will begin the data transfer. 6.2.4 Receive Descriptor Base Address (CR3) Bit Name Default Description 31:0 RDBA 00000000H, RW Receive Descriptor Base Address This register defines base address of receive descriptor-chain. The receive descriptor- polling command, after CR3 is set, will make DM9103 to fetch the descriptor at the Base-Address. This is a working register, so the value of reading is unpredictable. |
