PORT DISABLE CONFIGURATION (PRT_DIS_P[4:1] / PRT_DIS_M[4:1])
The PRT_DIS_P[4:1] and PRT_DIS_M[4:1] configuration straps are used in conjunction to disable the related port (4-1).
For PRT_DIS_Px (where x is the corresponding port 4-1):
0
= Port x D+ Enabled
1
= Port x D+ Disabled
For PRT_DIS_Mx (where x is the corresponding port 4-1):
0
= Port x D- Enabled
1
= Port x D- Disabled
3.4.3
NON-REMOVABLE PORT CONFIGURATION (CFG_NON_REM)
The CFG_NON_REM configuration strap is used to configure the non-removable port settings of the device to one of
five settings. These modes are selected by the configuration of an external resistor on the CFG_NON_REM pin. The
resistor options are a 200 kΩ pull-down, 200 kΩ pull-up, 10 kΩ pull-down, 10 kΩ pull-up, and 10 Ω pull-down, as shown
in Table 3-12.
3.4.4
BATTERY CHARGING CONFIGURATION (CFG_BC_EN)
The CFG_BC_EN configuration strap is used to configure the battery charging port settings of the device to one of five
settings. These modes are selected by the configuration of an external resistor on the CFG_BC_EN pin. The resistor
options are a 200 kΩ pull-down, 200 kΩ pull-up, 10 kΩ pull-down, 10 kΩ pull-up, and 10 Ω pull-down, as shown in
Table 3-13.
Note:
Both PRT_DIS_Px and PRT_DIS_Mx (where x is the corresponding port) must be tied to 3.3 V to disable
the associated downstream port. Disabling the USB 2.0 port will also disable the corresponding USB 3.1
Gen 1 port.
