All resets are applied asynchronously. That means, resets are not
synchronized to any internal clock. This ensures that the microcontroller can
be kept in reset state even if all internal clocks fail to operate.
The reset function provides two internal reset signals:
• System reset SYSRES
• Watchdog reset SYSRESWDT
Both resets provoke different reset behaviour of the Watchdog Timer. For
details refer to the “Watchdog Timer (WDT)“ on page 497.
Variable reset vector (flash memory devices only)
The flash memory devices allow to program the start address of the user’s
program, instead of starting at address 0000 0000
is stored in the extra area of the flash memory and can be written by an
external flash programmer or in self-programming mode.
