4.3.4 Extended
MOTOROLA
4-8
Extended instructions can access any address in memory with only three bytes.
The first byte is the opcode; the second and third bytes are the high and low
bytes of the operand's address.
When using the Motorola assembler, the programmer does not need to specify
whether an instruction is direct or extended.
selects the shortest form of the instruction. Table 4-4 lists the instructions that
use the extended addressing mode.
