NOTES:
1. External crystal circuity is not required if using the MCG internal clock option. For USB operation, an external crystal is required.
2. XTAL and EXTAL are the same pins as PTG4 and PTG5, respectively.
3. RC filters on RESET
and IRQ are recommended for EMC-sensitive applications.
4. R
PUDP
is shown for full-speed USB only. The diagram shows a configuration where the on-chip regulator and R
PUDP
are enabled.
The voltage regulator output is used for R
PUDP.
R
PUDP
can optionally be disabled if using an external pullup resistor on USBDP
5. V
BUS
is a 5.0 V supply from upstream port that can be used for USB operation.
6. USBDP and USBDN are powered by the 3.3 V regulator.
