Chapter 2: LPC24XX Memory mapping
read/fetch from 0x0000 0008 will provide data stored in 0x4000 0008. In case of
MEMMAP[1:0] = 00 (Boot Loader Mode), read/fetch from 0x0000 0008 will provide data
available also at 0x7FFF E008 (Boot ROM remapped from on-chip Bootloader).
MEMMAP[1:0] = 00 (Boot Loader Mode), read/fetch from 0x0000 0008 will provide data
available also at 0x7FFF E008 (Boot ROM remapped from on-chip Bootloader).
