4.4.2.5 Other Instructions
Besides the addressing modes outlined previously, some instructions use literal constants of various sizes. For example, BRA
(branch) instructions use 16-bit signed literals to specify the branch destination directly, whereas the DISI
instruction uses a 14-bit unsigned literal field. In some instructions, such as ULNK
, the source of an operand or result is implied by the opcode itself. Certain operations, such as a NOP
, do not have any operands.
