61 / 109 page ![]() Data Sheet ADIN1111 REGISTERS analog.com Rev. A | 61 of 109 Table 73. Bit Descriptions for TXSIZE Bits Bit Name Description Reset Access [31:14] RESERVED Reserved. 0x0 R [13:0] TX_SIZE Data in the Tx FIFO. Number of Half Words(16 Bit). 0x0 R Host Tx Frames Dropped Due to FIFO Overflow Register Address: 0x41, Reset: 0x00000000, Name: HTX_OVF_FRM_CNT Table 74. Bit Descriptions for HTX_OVF_FRM_CNT Bits Bit Name Description Reset Access [31:0] HTX_OVF_FRM_CNT Counts Host Tx Frames Dropped Due to FIFO Overflow. 0x0 R Address of a Detected ECC Error in Memory Register Address: 0x42, Reset: 0x00000000, Name: MECC_ERR_ADDR Table 75. Bit Descriptions for MECC_ERR_ADDR Bits Bit Name Description Reset Access [31:14] RESERVED Reserved. 0x0 R [13:0] MECC_ERR_ADDR Address of an Uncorrectable ECC Error in Memory. This is the address of the first uncorrectable ECC error detected. That is when either RX_ECC_ERR or TX_ECC_ERR assert. When RX_ECC_ERR and TX_ECC_ERR are cleared, the register is opened to catch the address of the next ECC error. SRAM is 16 bits wide and this address points to a location in SRAM. 0x0 R Corrected ECC Error Counters Register Address: 0x43 to 0x49 (Increments of 1), Reset: 0x00000000, Name: CECC_ERRn Table 76. Bit Descriptions for CECC_ERRn Bits Bit Name Description Reset Access [31:10] RESERVED Reserved. 0x0 R [9:0] CECC_ERR_CNT Corrected ECC Error Count. The counters map to FIFOs as follows: CECC_ERR[0] low priority Rx FIFO for P1CECC_ERR[1], high priority Rx FIFO for P1CECC_ERR[4] - Tx FIFO from the host. 0x0 R MAC Address Rule and DA Filter Upper 16 Bits Registers Address: 0x50 to 0x6E (Increments of 2), Reset: 0x00000000, Name: ADDR_FILT_UPRn Contains the upper 16 bits of a MAC address and the filtering rule associated with the MAC address. When writing the ADDR_FILT_x registers, two register locations must be written in order for a given table entry. For example, to write table entry 0, the registers must be written in the following order: 1. ADDR_FILT_UPR0. 2. ADDR_FILT_LWR0. Table 77. Bit Descriptions for ADDR_FILT_UPRn Bits Bit Name Description Reset Access 31 RESERVED Reserved. 0x0 R/W 30 APPLY2PORT1 Apply to Port 1. 0x0 R/W 0: do not apply to Port 1. Do not apply this table entry/rule to frames received on Port 1. |
