/* The K60N512VMD100 has 512Kb of FLASH beginning at address 0x0000:0000 and
 * 128Kb of SRAM beginning at address 0x1800:0000 (SRAM_L) and 0x2000:000
 * (SRAM_U).
 *
 * NOTE: that the first part of the K40 FLASH region is reserved for
 *       interrupt vectflash and, following that, is a region from 0x0000:0400
 *       to 0x0000:040f that is reserved for the FLASH control fields (FCF).
 *
 * NOTE: The on-chip RAM is split evenly among SRAM_L and SRAM_U. The RAM is
 *       also implemented such that the SRAM_L and SRAM_U ranges form a
 *       contiguous block in the memory map.
