00 = Minimum setting
BOREN1:BOREN0: Brown-out Reset Enable bits
11 = Brown-out Reset enabled in hardware only (SBOREN is disabled)
10 = Brown-out Reset enabled in hardware only and disabled in Sleep mode
01 = Brown-out Reset enabled and controlled by software (SBOREN is enabled)
00 = Brown-out Reset disabled in hardware and software
PWRTEN: Power-up Timer Enable bit
1 = PWRT disabled
