35 / 73 page  FP6606 35 FP6606- Preliminary 0.3-JUN-2018 Power Status Register (address = 0x1E) [reset =0x00] The power status register indicate the state of the FP6606. It is set by the FP6606 and read by the TCPM. The power status register is not latched and is continually updated unless powered off. Power Status Register 7 6 5 4 3 2 1 0 DEBUG_ACC _CONNECTE D TCPC_INIT_ STATUS SOURCING_ HIGH_VOLTA GE SOURCING_ VBUS VBUS_PRES _DETECT_E NABLED VBUS_PRES ENT VCONN_PRE SENT SINKING_VB US RU RU RU RU RU RU RU RU LEGEND: R/W = Read/Write; R = Read only Power Status Register Descriptions Bit Field Type Reset Description 7 DEBUG_ACC_CONNECTED RU 0 Debug Accessory Connected: Reflects the state of the DebugAccessoryConnected# output if supported. 0b: No Debug Accessory connected (default) 1b: Debug Accessory connected 6 TCPC_INIT_STATUS RU 0 TCPC Initialization Status 0b: The FP6606 has completed initialization and all registers are valid. 1b: The FP6606 is still performing internal initialization and the only registers that are guaranteed to return the correct values are 00h..0Fh. 5 SOURCING_HIGH_VOLTAGE RU 0 FP6606 does not support the function in this field. Please refer to vendor defined register. The VBUS control function is assigned to the Reg.0xD0~0xD2. 4 SOURCING_VBUS RU 0 FP6606 does not support the function in this field. Please refer to vendor defined register. The VBUS control function is assigned to the Reg.0xD0~0xD2. 3 VBUS_PRES_DETECT_ENABL ED RU 0 VBUS Present Detection Enabled: Indicates if the FP6606 is monitoring for VBUS Present or if the circuit has been powered off. 0b: VBUS Present Detection Disabled (Default) 1b: VBUS Present Detection Enabled 2 VBUS_PRESENT RU 0 VBUS present: The FP6606 shall report VBUS present when FP6606 detects VBUS rises above 4 V. The FP6606 shall report VBUS is not present when FP6606 detects VBUS falls below 3.5 V. The FP6606 may report VBUS is not present if VBUS is between 3.5 V and 4 V. 0b: VBUS Disconnected 1b: VBUS Connected 1 VCONN_PRESENT RU 0 VCONN present: If POWER_CONTROL.EnableVCONN (Reg.0x1C [0]) is disabled VCONN Present should be set to 0b. 0b: VCONN is not present 1b: This bit is asserted when VCONN present CC1 or CC2. Threshold is fixed at 2.4 V 0 SINKING_VBUS RU 0 FP6606 does not support the function in this field. Please refer to the Reg.0x85 [1] NMOS_SNK_ON. It is used to control sinking power path. |
