RESET
I
To enter the reset state, this pin must be kept 'L' for more that 2
μ
s (20
Φ
cycles
under normal Vcc conditions). If the crystal or ceramic resonator requires more
time to stabilize, extend this 'L' level time appropriately.
An external ceramic or quartz crystal oscillator can be connected between the
XCin and XCout pins. If an external clock source is used, connect the clock
source to the XCin pin and leave the XCout pin open.
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.
Loop filter for the frequency synthesizer.

An external capacitor (Ext. Cap) pin. When the USB transceiver voltage
converter is used, a 2
