release
Fig. 24.3 shows a comparison of the memory maps in Normal and Single Boot modes. In single Boot
mode, the on-chip flash memory is mapped to physical addresses (0x000_0000 through 0x4007_FFFF),
virtual addresses (0x0000_0000 through 0x0007_FFFF), and the on-chip boot ROM is mapped to
physical addresses 0x1FC0_0000 through 0x1FC0_0FFF.
For on-board programming, boot the TMP19A44F in Single Boot mode, as follows:
