Function
USB Data+ input/output signal.
USB Data- input/output signal.
Function
Boundary Scan Test Clock Input. There is no
internal pull device implemented. During
normal operation, it is recommended to
connect TCK to VSS.
Boundary Scan Test Data Input. An internal
pull-up device is connected to TDI. During
normal operation, TDI can be left open.
Function
External crystal input to the on-chip
oscillator. Clock input for direct driven clock
without using an external crystal. Function is
determined by the CLKMODE pin.
Output from the oscillator amplifier circuit. To
clock the C161U from an external source,
drive XTAL1, while XTAL2 leaving
unconnected. Minimum and maximum high/
low and rise/fall times specified in the AC
characteristics must be observed.
Clock Mode Select pin. CLKMODE must be
set to LOW if an external crystal is used. Set
to HIGH signal enables the direct clock input
path and switches the internal oscillator in
power down mode.
