I'm just starting off some work with the S12 series, specifically the DJ256. I am working out the memory mapping for the RAM, EE, and Registers.
Would someone with some more experience be able to comment if anything looks out of place?
My tentative configuration is:
INITEE 0x01 EEPROM mapped to 0x0000 - 0x0xFFF (4kB) and enabled
INITRM 0x39 RAM mapped to 0x1000 - 0x3FFF (12kB) and high-aligned
INITRG 0x40 Registers mapped to 0x4000 - 0x4800 (2kB)
Does this look okay? Is there a better configuration? And lastly, am I correct that the ROMHM bit in the MISC register should
be left at its default (unset, lower-half EE/ROM can be accessed)? I'd appreciate any help, thanks!
