CHAPTER 10: INSTRUCTION EXTENDER
10.6.8 Bit Operation Instructions
Types and functions of extended instructions
These extended instructions allow a memory address for manipulating bits to be specified with a symbol or
32-bit immediate.
Note: The second operand (imm3) used to specify a bit number does not cause an error in the ext33

providing that it is within the range of values represented by unsigned 32 bits. It is output as the
operand of a basic instruction directly as is. Note that the effective range of the basic
instructions is 3 unsigned bits.
