old ERC32 docs was Re: RTEMS code documentation references

[Jerry Needell]

The link below contains many of the old documents for the ERC32 and the 
TSC691/2/3 chipsets. The chapter and table references do not match the 
examples in the original request, but you may find these documents useful.

I hope it helps - Jerry
