Resource Mapping
Technical Data
88
unintended operations, a write to one of these registers should be
followed with a NOP instruction.
If conflicts occur when mapping resources, the register block will take
precedence over the other resources; RAM or EEPROM addresses
occupied by the register block will not be available for storage. When
active, BDM ROM takes precedence over other resources, although a
conflict between BDM ROM and register space is not possible. The
following table shows resource mapping precedence.
In expanded modes, all address space not used by internal resources is
by default external memory.
The MC68HC912DT128A contains 128K bytes of Flash EEPROM
nonvolatile memory which can be used to store program code or static
data. This physical memory is composed of four 32k byte array modules,
00FEE32K, 01FEE32K, 10FEE32K and 11FEE32K. The 32K byte array
11FEE32K has a fixed location from $4000 to $7FFF and $C000 to
$FFFF. The three 32K byte arrays 00FEE32K, 01FEE32K and
10FEE32K are accessible through a 16K byte program page window
mapped from $8000 to $BFFF. The fixed 32K byte array 11FEE32K can
also be accessed through the program page window.
