DATA RAM Reset at BROWN OUT (P89LPC922)

[Sudhir kunder]

Hello,
  Please help me whether on Brown out reset DATA RAM content also reset.
i.e. If I have enabled the brown out detect and my controller(P89LPC922) reset once its supply voltage drops to 2.5V or below and later when supply is set to normal voltage i.e 3.2V then data memory contents will reset or it will remain same as it was before the brown out was detected.

I think this forum is for programming support for the LPC9xx not for other general purpose LPC9xx questions..

try positing in the www.8052.com message forum or  www.nxp.com forum.

PS... below 1.5v is the data retention threshold
VDDR data retention voltage 1.5v ..... it's in the data sheet.
