Description
ULPI data pin 1
3-state output; plain input
ULPI data pin 0
3-state output; plain input
input I/O supply voltage; 3.0 V to 3.6 V; a 0.1 F decoupling
capacitor is recommended
resistor reference; connect through a 12 k

connect to the D pin of the USB connector
connect to the D+ pin of the USB connector
During UART mode, an internal 125 k
present on this pin.
select SDR or DDR ULPI interface:
plain input; TTL
input supply voltage or battery source; 3.0 V to 4.5 V
Remark: Below 3.0 V, USB full-speed and low-speed
transactions are not guaranteed to work, though some devices
may work with the ISP1705 at these voltages.
