Reset: controls the reset operations performed by the target device. The available options
vary with the selected device.
•
Autodetect selects the best suitable reset method for the target device. This can be a
specialized reset or standard method. If Autodetect finds an unknown device, it uses
the SYSRESETREQ method.
•
HW RESET performs a hardware reset by asserting the hardware reset (HW RESET)
signal.
•
SYSRESETREQ performs a software reset by setting the SYSRESETREQ bit. The
Cortex®-M core and on-chip peripherals are reset.
•
VECTRESET performs a software reset by setting the VECTRESET bit. Only the
Cortex
devices, VECTRESET is the only way they may be reset. However, VECTRESET is
not supported on Cortex
