RAM address. This address references the RAM location that stores the requested data.
The pointer can also be used to store 8-bit data when used as a temporary register. The
pointers are connected to the lower 8 bits of the D-bus. Instruction 1 loads Pointer 2,
RAM Bank0 with the value F2H.
Instruction 2, the register indirect address method is used to get the operand to multiply it
with the accumulator.
@P2:0. The data pointers access the lower 16 bits of each RAM bank. Instruction 8 uses
indirect addressing to PUSH information onto the stack.
commonly used to reference program memory. Instructions 5 and 6 display this addressing
method. Either pointer is automatically incremented to assist in transferring sequential
data.

511 (000H to 1FFH) is allowed. The accumulator is used in conjunction with this
method as a source or destination operand. Instruction 7 displays the accumulator as the
destination.

8-bit data in the operand to the specified RAM pointer.
The instruction format that specifies to the processor the action to be taken consists of the
Op Code, destination, source, and other special bits. The assembler makes this operation
transparent by providing mnemonics. Occasionally, the instruction format and
development code can assist in debugging. Examples to clarify the various instruction
formats and explain how specific bit patterns are developed and evaluated are provided
below.
Most instructions require one 16-bit word containing the information necessary for the
processor to execute the instruction correctly. This process requires one clock cycle for
execution. Immediate addressing, immediate operands, JUMP and CALL instructions
