Introduction
1.1 INTEGER UNIT USER PROGRAMMING MODEL
Figure 1-1 illustrates the integer portion of the user programming model. It consists of the
following registers:
1.1.1 Data Registers (D7 – D0)
These registers are for bit and bit field (1 – 32 bits), byte (8 bits), word (16 bits), long-word
(32 bits), and quad-word (64 bits) operations. They also can be used as index registers.
1.1.2 Address Registers (A7 – A0)
These registers can be used as software stack pointers, index registers, or base address
registers. The base address registers can be used for word and long-word operations.
Register A7 is used as a hardware stack pointer during stacking for subroutine calls and
exception handling. In the user programming model, A7 refers to the user stack pointer
(USP).
1-2
• 16 General-Purpose 32-Bit Registers (D7 – D0, A7 – A0)
• 32-Bit Program Counter (PC)
• 8-Bit Condition Code Register (CCR)
