Data Sheet — M68HC12B Family
NOTE:
The register block can be mapped to any 2-Kbyte boundary within the standard
64-Kbyte address space by manipulating bits REG15–REG11 in the register
initialization register (INITRG). INITRG establishes the upper five bits of the
register block’s 16-bit address. The register block occupies the first 512 bytes of
the 2-Kbyte block.
Default addressing (after reset) is indicated in
information, refer to
