PORT DISABLE CONFIGURATION (PRT_DIS_P[6:1] / PRT_DIS_M[6:1])

The PRT_DIS_P[6:1] and PRT_DIS_M[6:1] configuration straps are used in conjunction to disable the related port (6-1).

For PRT_DIS_Px (where x is the corresponding port 6-1):

0 = Port x D+ Enabled

1 = Port x D+ Disabled

For PRT_DIS_Mx (where x is the corresponding port 6-1):

0 = Port x D- Enabled

1 = Port x D- Disabled

200 kΩ Pull-Up

CONFIG2

Speed Indicator Mode + SMBus Slave Mode

The SMBus interface will operate in Slave Mode for use with hub configuration.

The following programmable pins will be re-purposed as USB Speed Indicator
