This bit has no effect if the Configuration bit, WDTEN, is enabled.
The SBOREN bit is only available when the BOREN1:BOREN0 Configuration bits = 01; otherwise, it is
disabled and reads as ‘0’. See Section 5.4 “Brown-out Reset (BOR)”.
This bit has no effect if the Configuration bit, WDTEN, is enabled.
