MOTOROLA
INSTRUCTION SET
MC68HC05CL48
14-2
REV 2.0
14.1.4 Extended
Extended instructions use only three bytes to access any address in memory. The
rst byte is the opcode; the second and third bytes are the high and low bytes of
the operand address.
When using the Motorola assembler, the programmer does not need to specify
whether an instruction is direct or extended. The assembler automatically selects
the shortest form of the instruction.
14.1.5 Indexed, No Offset
Indexed instructions with no offset are one-byte instructions that can access data
with variable addresses within the rst 256 memory locations. The index register
contains the low byte of the conditional address of the operand. The CPU auto-
matically uses $00 as the high byte, so these instructions can address locations
$0000–$00FF.
Indexed, no offset instructions are often used to move a pointer through a table or
to hold the address of a frequently used RAM or I/O location.
14.1.6 Indexed, 8-Bit Offset
Indexed, 8-bit offset instructions are two-byte instructions that can access data
with variable addresses within the rst 511 memory locations. The CPU adds the
unsigned byte in the index register to the unsigned byte following the opcode. The
sum is the conditional address of the operand. These instructions can access
locations $0000–$01FE.
Indexed 8-bit offset instructions are useful for selecting the kth element in an
n-element table. The table can begin anywhere within the rst 256 memory loca-
tions and could extend as far as location 510 ($01FE). The k value is typically in
the index register, and the address of the beginning of the table is in the byte fol-
lowing the opcode.
14.1.7 Indexed, 16-Bit Offset
Indexed, 16-bit offset instructions are three-byte instructions that can access data
with variable addresses at any location in memory. The CPU adds the unsigned
byte in the index register to the two unsigned bytes following the opcode. The sum
is the conditional address of the operand. The rst byte after the opcode is the
high byte of the 16-bit offset; the second byte is the low byte of the offset. These
instructions can address any location in memory.
Indexed, 16-bit offset instructions are useful for selecting the kth element in an
n-element table anywhere in memory.
As with direct and extended addressing, the Motorola assembler determines the
shortest form of indexed addressing.
