Micrel, Inc. KS8993M/ML/MI April 2005 57 M9999-041205 Register 20 (0x14): Port 1 Control 4 Register 36 (0x24): Port 2 Control 4 Register 52 (0x34): Port 3 Control 4 Bit Name R/W Description Default 7-0 Default tag [7:0] R/W Port’s default tag, containing 7-0: VID[7:0] 0x01 Note: Registers 19 and 20 (and those corresponding to other ports) serve two purposes: 1. Associated with the ingress untagged packets, and used for egress tagging. 2. Default VID for the ingress untagged or null-VID-tagged packets, and used for address lookup. Register 21 (0x15): Port 1 Control 5 Register 37 (0x25): Port 2 Control 5 Register 53 (0x35): Port 3 Control 5 Bit Name R/W Description Default 7-0 Transmit high priority rate control [7:0] R/W This register along with port control 7, bits [3:0] form a 12-bits field to determine how many “32Kbps” high priority blocks can be transmitted in a unit of 4Kbytes in a one second period). 0x00 Register 22 (0x16): Port 1 Control 6 Register 38 (0x26): Port 2 Control 6 Register 54 (0x36): Port 3 Control 6 Bit Name R/W Description Default 7-0 Transmit low priority rate control [7:0] R/W This register along with port control 7, bits [7:4] form a 12-bits field to determine how many “32Kbps” low priority blocks can be transmitted in a unit of 4 Kbytes in a one second period). 0x00 Register 23 (0x17): Port 1 Control 7 Register 39 (0x27): Port 2 Control 7 Register 55 (0x37): Port 3 Control 7 Bit Name R/W Description Default 7-4 Transmit low priority rate control [11:8] R/W These bits along with port control 6, bits [7:0] form a 12-bits field to determine how many “32Kbps” low priority blocks can be transmitted in a unit of 4Kbytes in a one second period). 0x0 3-0 Transmit high priority rate control [11:8] R/W These bits along with port control 5, bits [7:0] form a 12-bits field to determine how many “32Kbps” high priority blocks can be transmitted (in a unit of 4Kbytes in a one second period). 0x0 Register 24 (0x18): Port 1 Control 8 Register 40 (0x28): Port 2 Control 8 Register 56 (0x38): Port 3 Control 8 Bit Name R/W Description Default 7-0 Receive high priority rate control [7:0] R/W This register along with port control 10, bits [3:0] form a 12-bits field to determine how many “32Kbps” high priority blocks can be received in a unit of 4Kbytes in a one second period). 0x00 |
