Question about brown out feature

[valentin]

Hello,

I found this register field: RTC_CNTL_BROWN_OUT_CLOSE_FLASH_ENA which in the header file says it's hw reset value is 1, but in the he reference manual, the reset value is 0. I want to make use of the brown out feature, and I'm interested in:
- a description of this register field
- what's the actual hw reset value
- if I need to control this field to enable/disable some functionality

Thanks,
Valentin
