PRODUCTION DATA.
Bit No. | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
Reset State | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
Bit | Field | Type | Description |
---|---|---|---|
7:6 | RSVD | RO | Reserved. Read only, returns 0 when read. |
5 | bcdUSB30 | RW | This field when set will force SS hub to report bcdUSB = 3.0 instead of 3.2. |
4 | USB2.0_only | RW | USB 2.0 hub reports as 2.0 only. This bit disables the USB 2.0 hub from reporting 5Gbps support in the wSpeedsSupported field of the USB SS BOS SS device capability descriptor. This bit will also disable the USB3.0 hub.
This bit is read/write but the read value returned is the Boolean OR of this bit and the corresponding eFuse bit. If either bit is set, this feature is enabled. |
3 | USB2_DFP_UNCONF | RW | This field when set enables USB 2.0-defined Unconfigured state on DFPs. |
2 | I2C_100k | R/W | I2C 100kHz. This bit controls the clock rate of the I2C master for both USB to I2C requests . The EEPROM reads will occur at 400K unless eFuse is used to set the rate to 100k.
This bit is read/write but the read value returned is the Boolean OR of this bit and the corresponding eFuse bit. If either bit is set, this feature is enabled. |
1 | Galaxy_Enz | R/W | Disable Galaxy compatible modes. When this field is high, Galaxy charging compatible mode will not be included in AUTOMODE charger sequence.
This bit is read/write but the read value returned is the Boolean OR of this bit and the corresponding eFuse bit. If either bit is set, this feature is disabled. |
0 | FullAutoEn | R/W | Enable all divider battery charging modes. When automode is enabled and this bit is set, any DS port enabled for battery charging will attempt all divider battery charging modes before DCP, starting with the highest current option.
The bit is writable, but the value read back is the Boolean OR of this bit and the corresponding eFuse control. If either bit is set, eFuse or this register, this feature is enabled. |
