DCDC1 Under-voltage interrupt.
(Rising Edge triggered)
Note: This bit is cleared once read.
Interrupt mask.
0 = Do not mask interrupt.
1 = Mask interrupt.
Each bit in R36 enables or masks the
corresponding bit in R28. The default
value for these bits is 0 (unmasked).
Flag to indicate drain voltage can no
longer be regulated and output current
may be out of spec.
