This bit is set and cleared by software. It enables an interrupt to be generated
when the AVDF flag changes (toggles). The pending interrupt information is
automatically cleared when software enters the AVD interrupt routine
0: AVD interrupt disabled
1: AVD interrupt enabled
This read-only bit is set and cleared by hardware. If the AVDIE bit is set, an
interrupt request is generated when the AVDF bit changes value. Refer to

This bit indicates that the last reset was generated by the LVD block. It is set by
hardware (LVD reset) and cleared by software (writing zero). See WDGRF flag
description for more details. When the LVD is disabled by option byte, the LVDRF
bit value is undefined.
This bit indicates that the last reset was generated by the Watchdog peripheral. It is
set by hardware (watchdog reset) and cleared by software (writing zero) or an LVD
reset (to ensure a stable cleared state of the WDGRF flag when CPU starts).
