Chapter 3 Module Mapping Control (MMCV4) Block Description
unimplemented locations within the register space or to locations that are removed from the map (i.e., ports
A and B in expanded modes) will not cause this signal to become active. When the EMK bit is clear, this
pin is used for general purpose I/O.
3.4.3
The HCS12 core architecture limits the physical address space available to 64K bytes. The program page
index register allows for integrating up to 1M byte of FLASH or ROM into the system by using the six
page index bits to page 16K byte blocks into the program page window located from 0x8000 to 0xBFFF
in the physical memory space. The paged memory space can consist of solely on-chip memory or a
combination of on-chip and off-chip memory. This partitioning is configured at system integration through
the use of the paging configuration switches (pag_sw1:pag_sw0) at the core boundary. The options
available to the integrator are as given in
easy reference).
Based upon the system configuration, the program page window will consider its access to be either
internal or external as defined in

Memory Expansion
The partitioning as defined in
memory space and the actual on-chip memory sizes implemented in the
system may differ. Please refer to the device overview chapter for actual
sizes.
