Table 25. Bit Descriptions – USB 2.0 Port Polarity Control Register (continued)

p1_usb2pol

RORW

Downstream Port 1 DM/DP Polarity. This controls the polarity of the port.

0 = USB 2.0 port polarity is as documented by the pin out

1 = USB 2.0 port polarity is swapped from that documented in the

pin out, i.e. DM becomes DP, and DP becomes DM.

This bit is read only unless the customPolarity bit is set to 1. If

customPolarity is 0 the value of this bit reflects the value of the OTP

ROM p1_usb2pol bit.

p0_usb2pol

RO/RW

Upstream Port DM/DP Polarity. This controls the polarity of the port.

0 = USB 2.0 port polarity is as documented by the pin out

1 = USB 2.0 port polarity is swapped from that documented in the

pin out, i.e. DM becomes DP, and DP becomes DM.

This bit is read only unless the customPolarity bit is set to 1. If

customPolarity is 0 the value of this bit reflects the value of the OTP

ROM p0_usb2pol bit.

Description

7:0

langIdLsb

RO/RW

Language ID least significant byte. This register contains the value

returned in the LSB of the LANGID code in string index 0. The

TUSB8041 only supports one language ID. The default value of this

English United States.

When customStrings is 1, this field may be over-written by the contents

of an attached EEPROM or by an SMBus host.
