2.6.4
The CPU instructions consist of 2-byte (1-word) units. An instruction consists of an operation
field (op field), a register field (r field), an effective address extension (EA field), and a condition
field (cc).
Operation Field: Indicates the function of the instruction, the addressing mode, and the operation
to be carried out on the operand. The operation field always includes the first four bits of the
instruction. Some instructions have two operation fields.
Register Field: Specifies a general register. Address registers are specified by 3 bits, data registers
by 3 bits or 4 bits. Some instructions have two register fields. Some have no register field.
Effective Address Extension: Eight, 16, or 32 bits specifying immediate data, an absolute
address, or a displacement.
Condition Field: Specifies the branching condition of Bcc instructions.
Figure 2.12 shows examples of instruction formats.

Block transfer instruction. Transfers the number of data
bytes specified by R4L or R4 from locations starting at
the address indicated by ER5 to locations starting at the
address indicated by ER6. After the transfer, the next
instruction is executed.
