These steps can be verified by viewing the Flash memory addresses programmed using the dump
command on the HyperTerminal window. For details on the MSC8101ADS Flash loader utility, refer to
the C:\Program Files\Metrowerks\ CodeWarrior\CodeWarrior
Manuals\PDF\Targeting_Starcore.pdf file.
Table 1 shows MSC8101ADS switch settings if an application is running from MSC8101 internal
SRAM.
Table 2 shows specific MSC8101ADS switch settings if an application is running from Flash memory.

-->h0a000000 hff800018 program_word
Program the starting address of the application in the address table at location 0xFF800110. The
address table starts at 0xFE000110. The MSC8101ADS maps this address to 0xFF800110. The
following command loads a vector of 0xFF840000:
-->hff840000 hff800110 program_word
In this example, 0xFF840000 is the location where the address table starts in Flash memory. It
must match the starting address of the application defined in the *.lcf file (
_ROMStart
Program the application into Flash memory with the following command.
-->0 load_flash
The 0 (zero) option uses the addresses in the S-record to program the Flash memory.
Alternatively, if you specify the starting address in Flash memory in place of the 0, the data is
loaded in consecutive locations starting at the specified address (ignoring addresses in the
S-record). If there are gaps in the S-record address, these gaps are ignored.
Send the S-record application file (*.s) to be programmed in the Flash memory to the
MSC8101ADS using the

The MSC8101 (SC140) is placed in Debug mode immediately after reset.
Read the HRCW to come from the Altera gate array.
Read the HRCW to come from Flash memory.
Allows the application to execute the boot code after reset, which in turn
jumps to the application loaded in Flash memory.
Boot from external Flash memory (as opposed to the HI16 host port).
Normal processing mode after reset (instead of Debug mode).
