3
I/O
CMOS I/O port. These pins also functions as external interrupt 1 and are used
to enable the stealth detach function for the USB transceiver.
6
EXTCAP
_
An external capacitor (Ext. Cap) pin. When the USB transceiver voltage
converter is used, a 2.2
μ
F and a 0.1
μ
F capacitor should connect between this
pin and V
ss
to ensure proper operation of the USB line driver. This option is
enabled by setting bit 4 of the USB control register (000C
16
) to a “1”.

I
Input and output signals to and from the internal clock generation circuit.
Connect a ceramic resonator or quartz crystal between Xin and Xout pins to set
the oscillation frequency. If an external clock is used, connect the clock source
to the Xin pin and leave the Xout pin open.
