LED_PUL_STR_EN

Setting this bit enables pulse stretching for transmit, receive, or collision LED events so that very short

duration events are visible. The LED pulse stretching enable register indicates that the PHY must

stretch any pulses indicating transmit, receive, or collision. Without stretching, these pulses may be

too short to cause an LED to light.

LED_A_CFG

LED_0 configuration is made up of five bits. These four bits, Bits[3:0], are the LSBs and Bit 4 is from

LED_A_EXT_CFG_EN (LED_CTRL_1 register, Address 0x001B). The combination of the five bits configures LED_0,

selecting one of 32 possible configuration functions according to the following settings. The default setting is 01010 (on

if link up and blink on activity).
