Interrupts
Note:
50/139
AVD threshold selection register (AVDTHCR)
Reset value: 0000 0011 (03h)
Bits 7:5 = CK[2:0] internal RC Prescaler Selection
Bits 4:2 = Reserved, must be kept cleared.
Bits 1:0 = AVD[1:0] AVD Threshold Selection
Table 14.
Application notes
The LVDRF flag is not cleared when another Reset type occurs (external or watchdog), the
LVDRF flag remains set to keep trace of the original failure.
In this case, a watchdog reset can be detected by software while an external reset can not.
