Reset Value: 000x 000x (00h)
Bit 7:5 = Reserved.
Bit 4 = LVDRF LVD Reset Flag
This bit indicates when set that the last Reset was
generated by the LVD block. It is set by hardware
(LVD reset) and cleared by software (writing zero)
or a Watchdog Reset. See WDGRF flag descrip-
tion for more details.
Bit 3 = Reserved.
Bit 2 = CSSIE CSS Interrupt Enable
This bit allows to enable the interrupt when a dis-
trurbance is detected by the Clock Security Sys-
tem (CSSD bit set). It is set and cleared by soft-
ware.
0: Clock Filter interrupt disable
1: Clock Filter interrupt enable
Bit 1 = CSSD CSS Safe Osc. Detection
This bit indicates that the safe oscillator of the CSS
block has been selected. It is set by hardware and
cleared by reading the CRSR register when the
original oscillator recovers.
0: Safe oscillator is not active
1: Safe oscillator has been activated
Bit 0 = WDGRF WatchDog Reset Flag
This bit indicates when set that the last Reset was
generated by the Watchdog peripheral. It is set by
hardware (watchdog reset) and cleared by soft-
ware (writing zero) or an LVD Reset.
Combined with the LVDRF flag information, the
flag description is given by the following table.
