Description
Interface Protect Disable: Controls circuitry built into the ISP1506 to protect the ULPI interface
when the link 3-states STP and DATA[3:0]. When this bit is enabled, the ISP1506 will
automatically detect when the link stops driving STP.
0b — Enables the interface protect circuit (default). The ISP1506 attaches a weak pull-up
resistor on STP. If STP is unexpectedly HIGH, the ISP1506 attaches weak pull-down resistors
on DATA[3:0], protecting data inputs.
1b — Disables the interface protect circuit, detaches weak pull-down resistors on DATA[3:0],
and a weak pull-up resistor on STP.
Indicator Pass-through: The ISP1506 does not support the qualification of an external FAULT
with the internal V
or the V
logic 1.
0b — Not supported.
1b — The complement output signal is not qualified with the internal A_VBUS_VLD comparator.
The link must always set this bit to logic 1.
Indicator Complement: Informs the PHY to invert the FAULT input signal, generating the
complement output. For details, see
0b — The ISP1506 will not invert the FAULT signal (default).
1b — The ISP1506 will invert the FAULT signal.
reserved
Clock Suspend LOW: Active LOW clock suspend.
Powers down the internal clock circuitry only. By default, the clock will not be powered in 3-pin
serial mode.
Valid only in 3-pin serial mode. Valid only when SUSPENDM is set to logic 1, otherwise this bit
is ignored.
0b — Clock will not be powered in 3-pin serial mode (default).
1b — Clock will be powered in 3-pin serial mode.
reserved
3-Pin Full-Speed Low-Speed Serial Mode: Changes the ULPI interface to a 3-bit serial
interface. The PHY will automatically clear this bit when 3-pin serial mode is exited.
0b — Full-speed or low-speed packets are sent using the parallel interface (default).
1b — Full-speed or low-speed packets are sent using the 3-pin serial interface.
