The ISP1507 provides a built-in charge pump. To enable the charge pump, the link must
set the DRV_VBUS bit in the OTG_CTRL register (see
The ISP1507 also supports external 5 V supplies. The ISP1507 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_CTRL
register to logic 1. The link can optionally set both the DRV_VBUS and DRV_VBUS_EXT
bits to logic 1 to enable the external supply.

Table 9.
The ISP1507 supports external V
indicator signal. The indicator signal must be connected to the FAULT pin. To enable the
ISP1507 to monitor the digital fault input, the link must set the USE_EXT_VBUS_IND bit
in the OTG_CTRL register (see
INTF_CTRL register (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 ISP1507 and the link are described in the following subsections.
By default, the link must drive the ULPI bus to its idle state of 00h. To send commands and
USB packets, the link drives a nonzero value on DATA[7:0] to the ISP1507 by sending a
byte called TXCMD. Commands include USB packet transmissions, and register reads
and writes. Once the TXCMD is interpreted and accepted by the ISP1507, the NXT signal
is asserted and the link can follow up with the required number of data bytes. The TXCMD
byte format is given in
may result in undefined behavior.
Various TXCMD packet and register sequences are shown in later sections.
