Programming Model
2.2.1 User Programming Model
As Figure 2-3 shows, the user programming model consists of the following registers:
2.2.1.1 Data Registers (D0–D7)
Registers D0–D7 are used as data registers for bit, byte (8-bit), word (16-bit), and longword
(32-bit) operations. They may also be used as index registers.
2.2.1.2 Address Registers (A0–A6)
The address registers (A0–A6) can be used as software stack pointers, index registers, or
base address registers and may be used for word and longword operations.
2-6
• 16 general-purpose 32-bit registers, D0–D7 and A0–A7
• 32-bit program counter
• 8-bit condition code register
