1.3 Module Features
The following sections provide more details of the modules implemented on the MC9S12HY/HA family.
1.3.1 S12 16-Bit Central Processor Unit (CPU)
The S12 CPU is a high-speed, 16-bit processing unit that has a programming model identical to that of the
industry standard M68HC11 central processor unit (CPU).
• Full 16-bit data paths support efficient arithmetic operation and high-speed math execution
• Supports instructions with odd byte counts, including many single-byte instructions. This allows
much more efficient use of ROM space.
• Extensive set of indexed addressing capabilities, including:
— Using the stack pointer as an indexing register in all indexed operations
— Using the program counter as an indexing register in all but auto increment/decrement mode
