Reserved, set to 0x0.
00b = On - drive LED[5] low, off - drive LED[5] high.
01b = On - drive LED[5] high, off - drive LED[5] low.
10b = On - drive LED[5] low, off - tristate LED[5].
11b = On - drive LED[5] high, off - tristate LED[5].
00b = On - drive LED[4] low, off - drive LED[4] high.
01b = On - drive LED[4] high, off - drive LED[4] low.
10b = On - drive LED[4] low, off - tristate LED[4].
11b = On - drive LED[4] high, off - tristate LED[4].
If 19_3.3:2 is set to 11b, then 19_3.7:4 has no effect.
0000b = On - receive, off - no receive.
0001b = On - link, blink - activity, off - no link.
