MC68HC05G3 (705G4) Specification Rev. 1.1
4.3.5
INDEXED, NO OFFSET
In the indexed, no offset addressing mode, the effective address of the argument is
contained in the 8-bit index register. This addressing mode can access the first 256
memory locations ($0000-$00FF). These instructions are only one byte long. This mode is
often used to move a pointer through a table or to hold the address of a frequently
referenced RAM or I/O location.
4.3.6
INDEXED, 8-BIT OFFSET
In the indexed, 8-bit offset addressing mode, the effective address is the sum of the
contents of the unsigned 8-bit index register and the unsigned byte following the opcode.
The addressing mode is useful for selecting the K
th element in an n element table. With this
2-byte instruction, K typically would be in X with the address of the beginning of the table
in the instruction. As such, tables may begin anywhere within the first 256 addressable
locations and could extend as far as location 510 ($01FE). This is the last location which
can be accessed in this way.
4.3.7
INDEXED, 16-BIT OFFSET
In the indexed, 16-bit offset addressing mode, the effective address is the sum of the
contents of the unsigned 8-bit index register and the two unsigned bytes following the
opcode. This address mode can be used in a manner similar to indexed, 8-bit offset except
that this 3-byte instruction allows tables to be anywhere in memory. As with direct and
extended addressing, the Motorola assembler determines the shortest form of indexed
addressing.
4.3.8
BIT SET/CLEAR
In the bit set/clear addressing mode, the bit to be set or cleared is part of the opcode, and
the byte following the opcode specifies the direct addressing of the byte in which the
specified bit is to be set or cleared. Any read/write bit in the first 256 locations of memory,
including I/O, can be selectively set or cleared with a single 2-byte instruction.
4.3.9
BIT TEST AND BRANCH
The bit test and branch addressing mode is a combination of direct addressing and relative
addressing. The bit that is to be tested and its condition (set or clear) is included in the
opcode. The address of the byte to be tested is in the single byte immediately following the
opcode byte. The signed relative 8-bit offset in the third byte is added to the PC if the
specified bit is set or cleared in the specified memory location. This single 3-byte instruction
allows the program to branch based on the condition of any readable bit in the first 256
locations of memory. The span of branching is from -128 to +127 from the address of the
next opcode. The state of the tested bit also is transferred to the carry bit of the condition
code register.
4.3.10
INHERENT
In the inherent addressing mode, all the information necessary to execute the instruction is
contained in the opcode. Operations specifying only the index register and/or accumulator
as well as the control instruction with no other arguments are included in this mode. These
instructions are one byte long.
