Watchdog timer overflow
The Watchdog timer generates an internal reset when its 22-bit counter overflows. See
Watchdog Timer section for details.
USB reset
The USB reset is generated by a detection on the USB bus RESET signal. A single-end
zero on its upstream port for 4 to 8 times will set RSTF Bit in UISTA register. If Bit 6 (RSTE)
of the UIEN Register is set, the detection will also generate the RESET signal to reset the
CPU and other peripherals in the MCU.
