VII.8 Instruction Set
Instruction set has the following features:
The symbol "R" represents a register designator which specifies which one of the 64 registers (including
operational registers and general purpose registers) is to be utilized by the instruction. Bits 6 and 7 in R4
determine the selected register bank. "b'' represents a bit field designator which selects the number of the bit,
located in the register "R'', affected by the operation. "k'' represents an 8 or 10-bit constant or literal value.
(1) Every bit of any register can be set, cleared, or tested directly.
(2) The I/O register can be regarded as general register. That is, the same instruction can operates on I/O
register.
