Hi,

Pls refer to section 4.1 Memory Model in the Mcu_DSC_Compiler.pdf which I attached.

I copy part if it.

Eventually there are 3 program memory models (SPM, LPM, HPM) and 2 data memory
models (SDM, LDM) with peculiarities described below.
The compiler supports all the memory models pemrutations to compromise between
speed and size requirements. Some considerations how to choose memory model may be
found Working with the 56800E Memory Models.
These models being characterized by the following peculiarities and releated difficulties:
• Small program memory (SPM)
• Large program memory (LPM)
• Huge program memory (HPM)
• Small data memory (SDM)
• Large data memory (LDM)

Hope it can help you
