I have an MC9S12XEP768 configured with ROMHM = 0 (Internal flash), so from FD1000 to 0xFD1FFF I have the 4k RAM page window and then the 8K non paged ram section from 0x2000 to 0x3FFF.
Could I configure the section in the prm file to fix somehow the RPAGE register and use that RAM as a fixed 12K of non paged ram and make it transparent to the application?
And some secondary questions:
Why in the datasheet says that the RAM page starts in 0x1000 when in 0x1000 logical there are registers?
Can I make a placement like this?
RAM_FD = READ_WRITE 0xFD1000 TO 0xFD1FFF
RAM_2000 = READ_WRITE 0x2000 TO 0x3FFF
And then ?
INTO RAM_2000, RAM_FD1800;
Thanks in advance.
