[Icc-mot] Re: XGate support

Gene, you are right. XDP512 settings template is wrong. Data setting should 
be 0x1000 instead of 0x800.
Also upper '3' is missing in paged memory settings. It should be 
0x380000.0x3FFFFF instead of 0x80000.0xFFFFF. Does IDE mask these '3'?

Attachments aren't allowed here, but that my XDP512 map is short to be 
inserted into message body. Use fixed width font to see it properly. First 
column is a resource name, 2nd-global memory range, 3rd- S12X view in terms 
of PPAGE:offset, 4th - addresses from XGATE point of view, 5th - ICC memory 
settings. "-b" is a linker command line switch . For example you may 
add -bmyeeprom:0x800.0xFFF to define eeprom memory area.
