Note
:
The SVD internal circuit is initialized if the interrupt flag is cleared while SVD is in operation
after 1 is written to the SVDCTL.MODEN bit.

This bit enables low power supply voltage detection interrupts.
1 (R/W): Enable interrupts
0 (R/W): Disable interrupts
Notes:
•
If the SVDCTL.SVDRE[3:0] bits are set to 0xa, no low power supply voltage detection in-
terrupt will occur, as a reset is issued at the same timing as an interrupt.
•
To prevent generating unnecessary interrupts, clear the corresponding interrupt flag before
enabling interrupts.
