debug interface) and verifying that FLASH is blank. To avoid returning to secure mode after the next reset,
program the security bits (SEC) to the unsecured state (1:0).
4.4
The memory management unit (MMU) allows the program and data space for the HCS08 Family of
Microcontrollers to be extended beyond the 64K CPU addressable memory map. The extended memory
when used for data can also be accessed linearly using a linear address pointer and data access registers.
4.4.1
Key features of the MMU module are:
4.4.2
The HCS08 Core architecture limits the CPU addressable space available to 64K bytes. The Program Page
(PPAGE) allows for integrating up to 128K of FLASH into the system by selecting one of the 16K byte
blocks to be accessed through the Paging Window located at 0x8000-0xBFFF. The MMU module also
provides a linear address pointer that allows extension of data access up to 128K.
4.4.2.1
The PPAGE register holds the page select value for the Paging Window. The value in PPAGE can be
manipulated by using normal read and write instructions as well as the CALL and RTC instructions. The
user should not change PPAGE directly when running from paged memory, only CALL and RTC should
be used.
