Functional Description
Structure of 6809
The block diagram below shows the index arithmetic unit, the data ALU, command sequencer, memory fetch unit
and program counter.
Figure 2: Block Diagram
The memory interface contains registered read and write data and address registers, which makes the design of the
interface easier for timing verification etc.
Internal Registers
The following part describes the existing registers in the MC-ACT-6809:
Index Registers (X,Y)
The index registers are used in indexed mode of addressing and are used for calculating the effective addresses.
During some indexed modes, the contents of the index register are incremented or decremented to point to the next
item of tabular type data. All 4 pointer register (U, S, X, Y) can be used as index register.
Stack Pointer Registers (U,S)
The system stack pointer S is automatically used by the processor during subroutine calls and interrupts! The user
stack pointer is controlled by the programmer. Both stack pointers point to the top of the stack.
Program Counter Register
The program counter (PC) points to the address of the next instruction to be executed.
Accumulators (A,B,D)
The A and B accumulators are general purpose registers. Some instructions concatenate the registers A and B to
achieve 16 bit values. This register is then referred as the D register with the A register as most significant byte.
