D+ pull-up source. Power source for 1.5k pull-up resistor attached
to D+ during full-speed operation.
USB full-speed output buffer (D+). RSDP also functions as a
current sink for termination during high-speed operation.
USB high-speed I/O buffer (D+).
USB high-speed I/O buffer (D-).
USB full-speed output buffer (D-). RSDM also functions as a
current sink for termination during high-speed operation.
Active HIGH. ASIC fabrication and manufacturing test mode select.
These pins must be tied to GND during normal operation.
30-MHz crystal input.
30-MHz crystal output.
Active LOW. Media eject or remote wakeup requested. Tie to +3.3V
if functionality is not used.
Active HIGH. USB interrupt request. Tie to GND if functionality is not
used.
Configurable polarity. Device Presence Detect. This pin must not
be allowed to float if functionality is not utilized.
Active HIGH. ATA interface enable.
‘1’ = normal ATA operation
‘0’ = High-Z ATA interface pins and ATA interface logic halted
General purpose I/O pins. The GPIO pins must be tied to GND if
functionality is not utilized. If the hs_indicator config bit is set, the
GPIO2_nHS pin will reflect the operating speed of the device.
‘1’ = full-speed operation
‘0’ = high-speed operation
Active HIGH. ASIC test pin. This pin must be tied to GND during
normal operation.
Active HIGH. USB suspend indicator.
‘0’ = Chip active. VBUS power up to 100 mA granted.
‘High-Z’ = Chip suspend. VBUS system current limited to USB
suspend mode value.
Active LOW. Asynchronous chip reset.
Active LOW. ATA reset signal.
Active HIGH. ASIC test pins. These pins must be tied to GND during
normal operation.
ATA data signals.
ATA control signal.
ATA control signal.
