Russell,

I find the MSC1211 to be wonderful part and quite easy to apply. The source for answering questions i find most useful, personnally, is the many well annotated example programs which TI/BB have published.

There is a Yahoo MSC group ( TI-MSC@yahoogroups.com )which actively discusses the MSC1211 and is a great place to do some research on any question you may encounter in the future.

Regarding changing the HCR Registers:

Using the Downloader just "check" the erase Hardware Config and ensure you include the new HCR values in the downloaded file.

As an example:

Your assembly file would include a statement such as:

	org	807EH

HCR1:
	db	0FCH		;Enable External Memory
HCR0:
	db	0FFH		;Enable 1k Data Flash

You can leave this in your file when you download in the future just do not "check" the Erase Hardware Config option after the initial load (unless you intend to change it).

regards,
p
