Instruction Formats
Figure 29-1
the general format of the instructions, the opcode portion of the instruction word varies from
3-bits to 6-bits of information. This is what allows the midrange instruction set to have 35 instruc-
tions.
All instruction examples use the following format to represent a hexadecimal number:
where h signifies a hexadecimal digit.
To represent a binary number:
where b is a binary string identifier.
