Data Sheet
In most cases 32 bytes are not sufficient for a complete loader program. Therefore this
code will normally be used as a pre-loader to copy the main loader program to internal
RAM with start address 00’FA60
00’FDFF
After the reception of the main loader, the 32-byte pre-loader performs a jump to the start
address of this program.
