68HC11 Instruction Set
Addressing Modes Whenever an instruction operates on a data or operand we need to specify the location were the data resides An addressing mode refers to the way we specify the address or location where the data is stored Inherent Immediate Direct Indexed |
Is there an ASCII code for a Motorola 68HC11?
An old competing IBM standard, the EBCDIC code, is largely defunct except on some of their mainframes, but modern computer scientists are presently devising a 16-bit international character code. In the back of the Motorola 68HC11 programmer's handbook is a table of the ASCII codes.
What data types does 68HC11 support?
The 68HC11 supports a few different "data types," or ways of representing numbers. Most high-level languages (like C) support many data types, such as integers, floating point numbers, strings, and arrays. In assembly language, a programmer is given only "the bits" and must build more complex data types with subroutine libraries.
How does 68HC11 assembler work?
The 68HC11 assembler will automatically choose the direct addressing mode if the address specified is in the range $00 to $FF. Extended addressing could also be used to access this portion of memory, but it would rarely be preferable. The indexed addressing mode uses the X or Y register as a pointer into memory.
What is relative addressing 68HC11?
Relative addressing is only used in branching instructions. Offsets range in value from -128 to +127, allowing jumps both forward and backward in the instruction stream. The 68HC11 supports a few different "data types," or ways of representing numbers.

Arithmetic Operations
Microprocessors give the programmer a standard set of arithmetic and logical operationsthat can be performed upon numeric data. The 68HC11 provides instructions that work on both eight-bit data values (such as the Aor B registers or memory bytes) and sixteen-bit data values (such as the X and Y indexregisters). Earlier processors provided only eigh
Signed and Unsigned Binary Numbers
There are two methods of representing binary numbers that are commonly used bymicroprocessors. Using these two methods, the same string of 1's and 0's that comprise abyte or word can represent two different numbers, depending on which method is being used. The two methods are: unsigned binary format and two's-complement signedbinary format. The uns
