5 CENTRAL PROCESSING UNIT
5.1 INTRODUCTION
This CPU has a full 8-bit architecture and contains
six internal registers allowing efficient 8-bit data
manipulation.
5.2 MAIN FEATURES
s
Enable executing 63 basic instructions
s
Fast 8-bit by 8-bit multiply
s
17 main addressing modes (with indirect
addressing mode)
s
Two 8-bit index registers
s
16-bit stack pointer
s
Low power HALT and WAIT modes
s
Priority maskable hardware interrupts
s
Non-maskable software/hardware interrupts
5.3 CPU REGISTERS
The 6 CPU registers shown in Figure 8 are not
present in the memory mapping and are accessed
by specific instructions.
Accumulator (A)
The Accumulator is an 8-bit general purpose reg-
ister used to hold operands and the results of the
arithmetic and logic calculations and to manipulate
data.
Index Registers (X and Y)
These 8-bit registers are used to create effective
addresses or as temporary storage areas for data
manipulation. (The Cross-Assembler generates a
precede instruction (PRE) to indicate that the fol-
lowing instruction refers to the Y register.)
The Y register is not affected by the interrupt auto-
matic procedures.
Program Counter (PC)
The program counter is a 16-bit register containing
the address of the next instruction to be executed
by the CPU. It is made of two 8-bit registers PCL
(Program Counter Low which is the LSB) and PCH
(Program Counter High which is the MSB).
