The interface protect feature can be disabled by setting the INTF_PROT_DIS bit to logic 1.
The use of the RESET_N pin is optional. When RESET_N is asserted (LOW), the
ISP1505 will assert DIR. All logic in the ISP1505 will be reset, including the analog
circuitry and ULPI registers. During reset, the link must drive DATA[7:0] and STP to LOW;
otherwise undefined behavior may result. When RESET_N is deasserted (HIGH), the DIR
output will deassert (LOW) four or five clock cycles later.
interface behavior when RESET_N is asserted (LOW), and subsequently deasserted
(HIGH). If RESET_N is not used, it must be connected to V
The ISP1505 supports external 5 V supplies. The ISP1505 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. When the DRV_VBUS_EXT bit is set, the DRV_VBUS bit can be set to
any value and will be ignored.
The ISP1505 supports external V
circuit is required for host applications that supply more than 100 mA on V
between 4.75 V to 5.25 V. For low-power applications supplying less than 100 mA, the
V
link can utilize the internal A_VBUS_VLD comparator.
The ISP1505 supports external V
indicator signal. The indicator signal must be connected to the V
the ISP1505 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
