BOD Control Reg Default value

Hi, I am working on LPC54114 with LPCOpen 3.0 and doing some investigation of BOD.

I didn't initialize BOD in my code but found after boot up, the BOD control register default value is 0x04, which means the BOD reset is enabled. However, according to the user manual, the reset value of it is 0x00. They don't match. Why the BOD is on by default? Is that because of some ROM code that I can't see?

Best,

Chuan

Hi Chuan Tian,

The reason why BOD control register was not in a 0x00 reset value, it's because has an offset of 0x044, that's the reason why the BOD reset is enabled although you did not initialize in your code.

regards,
Miguel

Hi Miguel,

I don't think your answer is correct. Offset is not the value. Check this link out.
