Cable Diagnostics Cable Length Estimate Register

Address: 0xBA25, Reset: 0x00FF, Name: CDIAG_CBL_LEN_EST

This register provides an estimate of the cable length in meters based on the signal processing and is estimated during link establishment for

100BASE-TX and 1000BASE-T.

LED Pulse Stretching Duration Register

Address: 0xBC00, Reset: 0x0011, Name: LED_PUL_STR_DUR

When the LED_PUL_STR_DUR_SEL bit field in the LED_CTRL_1 register (Address 0x001B, Bits[3:2]) is set to 2'b11, the

LED_PUL_STR_DUR register determines the LED pulse stretching duration.

LED_PUL_STR_DUR

When the LED_PUL_STR_DUR_SEL bit field in the LED_CTRL_1 register (Address 0x001B, Bits[3:2]) is set

to 2'b11, the LED_PUL_STR_DUR bit field determines the LED pulse stretching duration. Multiply the value

specified by 8 to determine the duration in milliseconds.

LED Active Low Status Register

Address: 0xBC01, Reset: 0x0000, Name: LED_A_INV_EN

When this register is set, it specifies that the LED_0 output signal is active low. Note that the PHY is capable of automatically sensing whether

the LED_0 is active high or low. Note that the default value of this register bit is configurable via the hardware configuration pins. The hardware

configuration pin allows the default operation of the PHY to be configured in unmanaged applications. The default state depends on the

hardware strapping configuration on LED_0. For Mode 1 and Mode 2, this register returns to 0, whereas for Mode 3 and Mode 4, this register

defaults to 1.
