November 2017 I found on page 597 in the paragraph just above tabe 621 the following sentence "Serial flash devices respond to commands sent by software or automatically sent by the SPIFI when software reads <EM><STRONG>either of the <SPAN style="text-decoration: underline;">two</SPAN> read-only <SPAN style="text-decoration: underline;">serial flash regions</SPAN></STRONG> </EM>in the memory map". Below this is table 621 which only shows one region. I would like to know where the other region is located. Or can it be that LPC546xx only supports one serial flash region?</P><P></P><P>Dani</P></BODY></HTML> Thu, 14 Feb 2019 12:31:34 GMT danielgull 2019-02-14T12:31:34Z LPC546xx two serial flash regions? https://community.nxp.com/t5/LPC-Microcontrollers/LPC546xx-two-serial-flash-regions/m-p/864282#M34467 <HTML><HEAD></HEAD><BODY><P>Hi NXP community</P><P></P><P>While reading User Manual UM10912 Revision 2.1 9.
