48MHz USB Clock input. Use as USB clock
input when USB clock PLL is bypassed.
VDD for USB; connect to 3.3V power
supply.
VSS for USB; connect to ground.
USB Suspend output. This pin is high
when GO7007 goes into suspend mode.
USB Suspend Loop Back. Usually
connected to SUSPEND via R-C network
for a delayed start of internal clock when
GO7007 resumes from suspend state.
USB/HPI Select input. Tying pin to VDD
will enable USB functionality and disable
HPI interface. To use only HPI interface,
tie pin to VSS. Pin status will be sampled
only upon power-on reset.
USB Reset Enable. Tie pin to logic 1 for
USB bus to reset other parts of GO7007.
To disable this feature, connect pin to
ground. Changing the status of this pin
after power-on will have no effect.
General Purpose I/O pins programmed as
input or output on a pin-by-pin basis.
Global Reset input. Setting pin low (at
least 100µs) will reset GO7007 (active
low).
