Table 13. USB Module Signals (continued)
This signal is one half of the differential NRZI formatted output from
the module. It is fed to the transmitted D+ input of the analog front
end.
This signal is an active low output enable for the differential drivers on
the analog front end. When this signal is active, the differential drivers
will drive the USB. When this signal is inactive, the differential drivers
will tristate their outputs.
Can be programmed to cause events to occur in first platform timer. It
can either clock the event counter or provide a trigger to the timer
value capture logic.
The output from first platform timer.
Can be programmed to cause events to occur in the second platform
timer. This can either clock the event counter or provide a trigger to the
timer value capture logic.
The output from the second platform timer.
Can be programmed to cause events to occur in the third platform
timer. It can either clock the event counter or provide a trigger to the
timer value capture logic.
The output from the third platform timer.
Can be programmed as an input that causes events to occur in the
fourth platform timer. This can either clock the event counter or
provide a trigger to the timer value capture logic.
The output from the fourth platform timer.
