2.8.7 Immediate—#xx:8, #xx:16, or #xx:32
The operand value is 8-bit (#xx:8), 16-bit (#xx:16), or 32-bit (#xx:32) data included in the
instruction code. This addressing mode has short formats in which 3- or 4-bit immediate data can
be used.
When the size of immediate data is less than that of the operand size (byte, word, or longword),
the immediate data is zero-extended.
The ADDS, SUBS, INC, and DEC instructions contain immediate data implicitly. Some bit
manipulation instructions contain 3-bit immediate data in the instruction code, specifying a bit
number. The BFLD and BFST instructions contain 8-bit immediate data in its instruction code,
specifying bit numbers. The TRAPA instruction contains 2-bit immediate data in its instruction
code, specifying a vector address.
