59 / 109 page  Data Sheet ADIN1111 REGISTERS analog.com Rev. A | 59 of 109 Table 68. Bit Descriptions for MAC_RST_STATUS Bits Bit Name Description Reset Access [31:2] RESERVED Reserved. 0x0 R 1 MAC_CRYSL_CLK_RDY MAC Crystal Clock Ready. If 0, this field indicates that the MAC core has not been released from reset. If 1, this field indicates that the MAC core is released from reset. The MAC core is released from reset when the crystal clock (25 MHz) is ready. 0x1 R 0 MAC_OSC_CLK_RDY MAC Oscillator Clock Ready. 0x1 R Software Reset Register Address: 0x3C, Reset: 0x00000000, Name: SOFT_RST Table 69. Bit Descriptions for SOFT_RST Bits Bit Name Description Reset Access [31:16] RESERVED Reserved. 0x0 R [15:0] RST_KEY Software Reset. Write a pair of keys in order and back to back on the SPI to trigger a reset. 0x0 W 0x4F1C: Key 1 to reset the MAC logic only. 0xC1F4: Key 2 to reset the MAC logic only. Reset does not take effect until CS is brought high, and CS must be held asserted for at least 100 ns for the reset to take effect. If the MAC-PHY is in software power-down mode, the MAC_ONLY reset has no effect. That is, CRSM_SFT_P_CNTRL.CRSM_SFT_PD must be 0. 0x6F1A: Key 1 to request release of reset to the MAC core logic. Use MAC_RST_EXIT_REQ_KEYx to request a release of reset to the MAC core logic when the 25 MHz crystal clock is not available. This brings the MAC out of reset using the oscillator clock (12.5 MHz to 25.7 MHz). SPI accesses can then proceed at 15 MHz to allow debug access to MAC and PHY registers. 0xA1F6: Key 2 to request release of reset to the MAC core logic. Inject an Error on MISO from the DUT Register Address: 0x3D, Reset: 0x00000000, Name: SPI_INJ_ERR Table 70. Bit Descriptions for SPI_INJ_ERR Bits Bit Name Description Reset Access [31:1] RESERVED Reserved. 0x0 R 0 TEST_SPI_INJ_ERR Inject an Error on the SPI MISO Path. This function allows software to test that errors received on MISO are properly detected in software. If set and using the OPEN Alliance SPI protocol for data transaction, the parity bit in the Rx footer is inverted. Also, the time stamp parity bit in the in Rx footer is inverted. If set and using the OPEN Alliance SPI protocol for protected control burst write transactions, starting from the second word in a burst, the MS bit of each echoed 32-bit word is inverted. If set and using the OPEN Alliance SPI protocol for protected control read transactions, the MS bit of each 32-bit complement word is inverted. If set and using the generic SPI protocol with protection enabled, the CRC8 returned on a register read is inverted. 0x0 R/W FIFO Sizes Register Address: 0x3E, Reset: 0x00000464, Name: FIFO_SIZE Before modifying the FIFO sizes, frame reception and transmission must be stopped and the FIFOs must be empty. Configure the forwarding rules to drop all frames and set P1_UNK2HOST to 0 to ensure all received frames are dropped. Use RXF_CLR & TXF_CLR to reset the FIFOs. Then, the FIFO sizes can be modified. The total FIFO size must be less than or equal to 28 kB. |
