USB 2.0 Port Polarity Control Register Field Descriptions (continued) Bit Field Type Reset Description 0 p0_usb2pol R/RW 0 Upstream port DM/DP polarity This bit controls the polarity of the port. 0 = USB 2.0 port polarity is as shown in the pinout. 1 = USB 2.0 port polarity is swapped from that shown in the pinout (that is, 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. 8.5.13 UUID Byte N Register Offset = 10h-1Fh Figure 14. UUID Byte N Register 7 6 5 4 3 2 1 0 uuidByte[n] R-X Table 15. UUID Byte N Register Field Descriptions Bit Field Type Reset Description 7:0 uuidByte[n] R X UUID byte N The UUID returned in the Container ID descriptor. The value of this register is provided by the device and meets the UUID requirements of the Internet Engineering Task Force (IETF) RFC 4122 A UUID URN Namespace. 8.5.14 Language ID LSB Register Offset = 20h, reset = 09h Figure 15. Language ID LSB Register 7 6 5 4 3 2 1 0 langIdLsb[7:4] langIdLsb[3] langIdLsb[2:1] langIdLsb[0] R/RW-0 R/RW-1 R/RW-0 R/RW-1 Table 16. Language ID LSB Register Field Descriptions Bit Field Type Reset Description 7:4 langIdLsb[7:4] R/RW 0 Language ID least significant byte This register contains the value returned in the LSB of the LANGID code in string index 0. The TUSB4041I device only supports one language ID. The default value of this register is 09h representing the LSB of the LangID 0409h indicating English United States. When the customStrings bit is set to 1, this field may be overwritten by the contents of an attached EEPROM or by an SMBus host. 3 langIdLsb[3] R/RW 1 2:1 langIdLsb[2:1] R/RW 0 0 langIdLsb[0] R/RW 1 |
