PHYAD1
I/O
LED Output:
Programmable LED2 Output /
Configuration Mode:
The pull-up/pull-down value is latched as PHYADD[1]
during power-up / reset. See “Strapping Options”
section for details.
The LED2 pin is programmed via register 11h bits [7:6], LED_SEL[1:0], and is
defined as follows:
LED_SEL[1:0] = (1,1)
// 6-LED Configuration (default)
