2 CENTRAL PROCESSING UNIT
2.1 INTRODUCTION
The CPU has a full 8-bit architecture. Six internal
registers allow efficient 8-bit data manipulation.
The CPU is capable of executing 63 basic instruc-
tions and features 17 main addressing modes.
2.2 CPU REGISTERS
The 6 CPU registers are shown in the program-
ming model in Figure 2, on page 12. Following an
interrupt, all registers except Y are pushed onto
the stack in the order shown in Figure 3, on
page 13. They are popped from stack in the re-
verse order.
The Y register is not affected by these automatic
procedures. The interrupt routine must therefore
handle Y, if needed, through the PUSH and POP
instructions.
Accumulator (A).
The Accumulator is an 8-bit
general purpose register used to hold operands
and the results of the arithmetic and logic calcula-
tions as well as data manipulations.
Index Registers (X and Y).
These 8-bit registers
are used to create effective addresses or as tem-
porary storage areas for data manipulation. The
Cross-Assembler generates a PRECEDE instruc-
tion (PRE) to indicate that the following instruction
refers to the Y register.
Program Counter (PC).
The program counter is a
16-bit register containing the address of the next
instruction to be executed by the CPU.
