Central Processing Unit (CPU)
This CPU has a full 8-bit architecture and contains six internal registers allowing efficient 8-bit data
manipulation.
2.1
Main Features
● Enable executing 63 basic instructions
● Fast 8-bit by 8-bit multiply
● 17 main addressing modes (with indirect addressing mode)
● Two 8-bit index registers
● 16-bit stack pointer
● 8 MHz CPU internal frequency (9 MHz maximum)
● Wait and Halt Low Power modes
● Maskable hardware interrupts
● Non-maskable software interrupt
2.1.1
CPU Registers
The 6 CPU registers shown in Figure 5 are not present in the memory mapping and are accessed
by specific instructions.
Accumulator (A)
The Accumulator is an 8-bit general purpose register that holds operands and results of arithmetic
and logic calculations. It also manipulates data.
Index Registers (X and Y)
In indexed addressing modes, these 8-bit registers are used to create either effective addresses or
temporary storage areas for data manipulation. (The Cross-Assembler generates a previous
instruction (PRE) to indicate that next instruction refers to the Y register.)
The Y register is not affected by interrupt automatic procedures (not pushed to and popped from the
stack).
Program Counter (PC)
The program counter is a 16-bit register containing the address of next instruction the CPU
executes. The program counter consists of two 8-bit registers:
PCL (Program Counter Low which is the LSB)
PCH (Program Counter High which is the MSB).
