Staggered

1. Pin 11, before PHY initialization, is used

 

 

Spin/LED

to detect staggered spin up. If Pin 11 is

 

 

 

grounded Drives spin up on power. If Pin 11

 

 

 

is no-connect, the drive will not spin up

 

 

 

until host initiates the PHY initialization rou-

 

 

 

tine.

 

 

 

2. Pin 11, after PHY initialization, is used

 

 

 

for driving LED Activity. The device pro-

 

 

 

vides a low voltage-current driver to drive

 

 

 

the LED activity signal.
