BCDEN_R

Field BCDEN reader - Battery charging detector (BCD) enable Device mode This bit is set by the software to enable the BCD support within the USB device. When enabled, the USB PHY is fully controlled by BCD and cannot be used for normal communication. Once the BCD discovery is finished, the BCD should be placed in OFF mode by clearing this bit to ’0 in order to allow the normal USB operation.

BCDEN_W

Field BCDEN writer - Battery charging detector (BCD) enable Device mode This bit is set by the software to enable the BCD support within the USB device. When enabled, the USB PHY is fully controlled by BCD and cannot be used for normal communication. Once the BCD discovery is finished, the BCD should be placed in OFF mode by clearing this bit to ’0 in order to allow the normal USB operation.

DCDEN_R

Field DCDEN reader - Data contact detection (DCD) mode enable Device mode This bit is set by the software to put the BCD into DCD mode. Only one detection mode (DCD, PD, SD or OFF) should be selected to work correctly.

DCDEN_W

Field DCDEN writer - Data contact detection (DCD) mode enable Device mode This bit is set by the software to put the BCD into DCD mode. Only one detection mode (DCD, PD, SD or OFF) should be selected to work correctly.

DCDET_R

Field DCDET reader - Data contact detection (DCD) status Device mode This bit gives the result of DCD.

DPPU_DPD_R

Field DPPU_DPD reader - DP pull-up / DPDM pull-down Device mode This bit is set by software to enable the embedded pull-up on DP line. Clearing it to ’0 can be used to signal disconnect to the host when needed by the user software. Host mode This bit is set by software to enable the embedded pull-down on DP and DM lines.

DPPU_DPD_W

Field DPPU_DPD writer - DP pull-up / DPDM pull-down Device mode This bit is set by software to enable the embedded pull-up on DP line. Clearing it to ’0 can be used to signal disconnect to the host when needed by the user software. Host mode This bit is set by software to enable the embedded pull-down on DP and DM lines.

PDEN_R

Field PDEN reader - Primary detection (PD) mode enable Device mode This bit is set by the software to put the BCD into PD mode. Only one detection mode (DCD, PD, SD or OFF) should be selected to work correctly.

PDEN_W

Field PDEN writer - Primary detection (PD) mode enable Device mode This bit is set by the software to put the BCD into PD mode. Only one detection mode (DCD, PD, SD or OFF) should be selected to work correctly.

PDET_R

Field PDET reader - Primary detection (PD) status Device mode This bit gives the result of PD.

PS2DET_R

Field PS2DET reader - DM pull-up detection status Device mode This bit is active only during PD and gives the result of comparison between DM voltage level and VLGC threshold. In normal situation, the DM level should be below this threshold. If it is above, it means that the DM is externally pulled high. This can be caused by connection to a PS2 port (which pulls-up both DP and DM lines) or to some proprietary charger not following the BCD specification.

Register BCDR reader

SDEN_R

Field SDEN reader - Secondary detection (SD) mode enable Device mode This bit is set by the software to put the BCD into SD mode. Only one detection mode (DCD, PD, SD or OFF) should be selected to work correctly.

SDEN_W

Field SDEN writer - Secondary detection (SD) mode enable Device mode This bit is set by the software to put the BCD into SD mode. Only one detection mode (DCD, PD, SD or OFF) should be selected to work correctly.

SDET_R

Field SDET reader - Secondary detection (SD) status Device mode This bit gives the result of SD.
