This is where the BIN Hackers and definition junkies discuss the inner workings of the EEC code and hardware. General tuning questions do not go here. Only technical/hardware-specific/code questions and discussions belong here.

Operand Addressing, Opcode nuances

Post by jsa » Fri Oct 23, 2015 10:32 pm

8096 section of the 1985 Intel Microcontroller Handbook - wrote: 3.2. OPERAND ADDRESSING
Operands are accessed within the address space of the 8096 with one of six basic addressing modes. Some of
the details of how these addressing modes work are hidden by the assembly language
. If the programmer is to take
full advantage of the architecture, it is important that these details be understood. This section will describe the addressing
modes as they are handled by the hardware. At the end of this section the addressing modes will be
described as they are seen through the assembly language.

The six basic addressing modes which will be described are termed register-direct, indirect, indirect with auto-increment,
immediate, short-indexed, and long-indexed. Several other useful addressing operations can be achieved
by combining these basic addressing modes with specific registers such as the ZERO register or the stack pointer.
Applies equally to 8061 ?

Hidden, :confused:, no wonder.
