Hello All,

While I am studying the Data Sheet of MC9S12XE100 family I came across this Module Memory Mapping Control(Chapter 3 in Data Sheet)  By studying the description of the module I came to understand It is responsible for selection of memories and Peripherals of device(MC9S12XE100) internally and Externally.

How does MMC(Memory Mapping Control)  Module in S12 XE Devices affects the working of device means what happens if I program this module? and what Happens if I ignore the programming of this module will my device works properly or misbehave?

can someone explain the above query? Please....

Thanks in Advance:smileyhappy:

Thanks & Regards

Hello,

Please take a look at the attached S12XE memory map.

It shows the configuration of the GPAGE, PPAGE, RPAGE, EPAGE, MMCCTL1 registers.
