detector reset and clock supervisor reset.
Clock Super Visor (CSV)
Clocks generated by CR oscillators are used to supervise abnormality of the external clocks.
・
External OSC clock failure (clock stop) is detected, reset is asserted.
・
External OSC frequency anomaly is detected, interrupt or reset is asserted.
