10.8.1.3
Operands for immediate mode instructions are included in the instruction stream and are fetched into the
instruction queue along with the rest of the 16 bit instruction. The ’#’ symbol is used to indicate an
immediate addressing mode operand. This address mode is used for semaphore instructions.
Examples:
10.8.1.4
The 4 bit wide immediate addressing mode is supported by all shift instructions.
RD = RD ∗ IMM4
Examples:
10.8.1.5
The 8 bit wide immediate addressing mode is supported by four major commands (ADD, SUB, LD, CMP).
RD = RD ∗ imm8
Examples:
10.8.1.6
The 16 bit wide immediate addressing mode is a construct to simplify assembler code. Instructions which
offer this mode are translated into two opcodes using the eight bit wide immediate addressing mode.
RD = RD ∗ IMM16
Examples:
10.8.1.7
In this addressing mode only one operand is explicitly given. This operand can either be the source (f(RD)),
the target (RD = f()), or both source and target of the operation (RD = f(RD)).
