The ISP1504x1 supports external 5 V supplies. The ISP1504x1 can control the external
supply using the active-LOW PSW_N open-drain output pin. To enable the external supply
by driving PSW_N to LOW, the link must set the DRV_VBUS_EXT bit in the OTG Control
register to logic 1.

The ISP1504x1 supports external V
indicator signal. The indicator signal must be connected to the FAULT pin. To enable the
ISP1504x1 to monitor the digital fault input, the link must set the USE_EXT_VBUS_IND
bit in the OTG Control register and the IND_PASSTHRU bit in the Interface Control
register to logic 1. For details, see
The FAULT input pin is mapped to the A_VBUS_VLD bit in RXCMD. Any changes for the
FAULT input will trigger RXCMD carrying the FAULT condition with A_VBUS_VLD.
Commands between the ISP1504x1 and the link are described in the following
subsections.
