(3) Memory map
Figure 3.12.2 shows memory maps for multi chip and multi boot modes. When start
up in multi boot mode, internal boot ROM is mapped in FFF800H address, the boot
program starts up.
When start up in multi chip mode, internal boot ROM is mapped in 1F800H address,
it can be made to operate arbitrarily by the user. Program starting address is 1F800H.
