61 / 96 page  Data Sheet ADIN1300 REGISTER SUMMARY analog.com Rev. B | 61 of 96 Table 52. CLK_CNTRL Settings CLK_CNTRL RX_CLK TX_CLK No Link No Link 1000 Mbps Link 000 2.5 MHz Off Off 001 25 MHz 2.5 MHz Off 010 125 MHz 25 MHz Off 011 125 MHz 25 MHz Off 100 (Default) 2.5 MHz 2.5 MHz 2.5 MHz 101 25 MHz 25 MHz 25 MHz 110 125 MHz 2.5 MHz 2.5 MHz 111 125 MHz 25 MHz 25 MHz PHY Control 3 Register Address: 0x0017, Reset: 0x3048, Name: PHY_CTRL_3 This register provides access to PHY control register bits for link enable and autonegotiation controls. Table 53. Bit Descriptions for PHY_CTRL_3 Bits Bit Name Description Reset Access [15:14] RESERVED Reserved. 0x0 R 13 LINK_EN Setting this bit enables linking. If linking is disabled, the PHY enters the standby state and does not attempt to bring up links. The standby state can be used to run diagnostics, including cable diagnostics. 0x1 R/W 1: enable linking. 0: disable linking. [12:10] NUM_SPEED_RETRY If downspeed is enabled, this register bit specifies the number of retries the PHY must attempt to bring up a link at the advertised speed before advertising a lower speed. By default, the PHY attempts to bring up a link 5 times (4 retries) before downspeeding. 0x4 R/W [9:0] RESERVED Reserved. 0x48 R/W Interrupt Mask Register Address: 0x0018, Reset: 0x0000, Name: IRQ_MASK The interrupt mask register allows interrupts to be masked or unmasked. Table 54. Bit Descriptions for IRQ_MASK Bits Bit Name Description Reset Access [15:11] RESERVED Reserved. 0x0 R/W 10 CBL_DIAG_IRQ_EN Cable Diagnostics Interrupt Enable Bit. 0x0 R/W 1: enable cable diagnostics interrupt. 0: disable cable diagnostics interrupt. 9 MDIO_SYNC_IRQ_EN MDIO Synchronization Lost Interrupt Enable Bit. 0x0 R/W 1: enable MDIO synchronization lost interrupt. 0: disable MDIO synchronization lost interrupt. 8 AN_STAT_CHNG_IRQ_EN Autonegotiation Status Changed Interrupt Enable Bit. 0x0 R/W 1: enable autonegotiation status changed interrupt. 0: disable autonegotiation status changed interrupt. 7 FC_FG_IRQ_EN Frame checker/generator interrupt enable bit. 1: enabled frame checker/generator interrupt 0x0 R/W |
