Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7 | RSVD | R | 0 | Reserved Read only, returns 0 when read. |
6 | customBCfeatures | RW | 0 | Custom battery charging feature enable This bit controls the ability to write to the battery charging feature configuration controls. 0 = The HiCurAcpModeEn and cpdEN bits are read only and the values are loaded from the OTP ROM. 1 = The HiCurAcpModeEn and cpdEN, bits are R/W and can be loaded by EEPROM or written by SMBus from this register. This bit can be written simultaneously with HiCurAcpModeEn and cpdEN. |
5 | pwrctlPol | RW | X | Power enable polarity This bit is loaded at the deassertion of reset with the value of the 0 = PWRCTL polarity is active low. 1 = PWRCTL polarity is active high. When the TUSB4041I-Q1 device is in I2C mode, the TUSB4041I-Q1 device loads this bit from the contents of the EEPROM. When the TUSB4041I-Q1 device is in SMBUS mode, the value can be overwritten by an SMBus host. |
4 | HiCurAcpModeEn | R/RW | 0 | High-current ACP mode enable This bit enables the high-current tablet charging mode when the automatic battery charging mode is enabled for downstream ports. 0 = High-current divider mode disabled. Legacy current divider mode enabled. 1 = High-current divider mode enabled This bit is read only unless the customBCfeatures bit is set to 1. If customBCfeatures is 0, the value of this bit reflects the value of the |
3 | cpdEN | RRW | 0 | Enable device attach detection This bit enables device attach detection (such as a cell-phone detect) when auto mode is enabled. 0 = Device attach detect is disabled in auto mode. 1 = Device attach detect is enabled in auto mode. This bit is read only unless the customBCfeatures bit is set to 1. If |
2 | RSVD | RW | 0 | Reserved |
1 | autoModeEnz | RW | X | Automatic mode enable(1) This bit is loaded at the deassertion of reset with the value of the The automatic mode only applies to downstream ports with battery charging enabled when the upstream port is not connected. Under these conditions: 0 = Automatic mode battery charging features are enabled. 1 = Automatic mode is disabled; only battery-charging DCP mode is supported. |
0 | RSVD | R | 0 | Reserved Read only, returns 0 when read. |
