4.6.8 Use of CPU16 Indexed Mode to Replace M68HC11 Direct Mode
4.7 Instruction Set
4.7.1 Instruction Set Summary
M68HC16 Z SERIES
USER’S MANUAL
In M68HC11 systems, the direct addressing mode can be used to perform rapid ac-
cesses to RAM or I/O mapped from $0000 to $00FF. The CPU16 uses the first 512
bytes of bank 0 for exception vectors. To provide an enhanced replacement for the
M68HC11’s direct addressing mode, the ZK field and index register Z have been as-
signed reset initialization vectors. By resetting the ZK field to a chosen page and using
indexed mode addressing, a programmer can access useful data structures anywhere
in the address map.
The CPU16 instruction set is based on the M68HC11 instruction set, but the opcode
map has been rearranged to maximize performance with a 16-bit data bus. Most
M68HC11 code can run on the CPU16 following reassembly. The user must take into
account changed instruction times, the interrupt mask, and the changed interrupt stack
frame (refer to Transporting M68HC11 Code to M68HC16 Devices ,Freescale Pro-
gramming Note M68HC16PN01/D, for more information).
