Software Reset
The reset sequence can be triggered at any time via the protected instruction SRST
(Software Reset). This instruction can be executed deliberately within a program, such
as to exit bootstrap loader mode, or upon a hardware trap that reveals a system failure.
Note: A software reset only latches the configuration of the bus interface (BUSTYP) from
Watchdog Timer Reset
If the Watchdog Timer (WDT) is not disabled during the initialization or serviced regularly
during program execution, it will overflow and trigger the reset sequence. Other than
after hardware and software reset, the watchdog reset completes a running external bus
cycle. Then the internal reset sequence is started.
