(2) Register addressing (via register)
10.1.2 Operand addresses
(1) Register addressing
(2) Immediate addressing
(3) Based addressing
The contents of the general-purpose register (r0-r31) designated in the instruction are transferred to the program
counter (PC).
The JMP instruction uses this addressing.
In this addressing mode, the general-purpose register designated in the general-purpose register designation field
is accessed as an operand. This addressing is used by instructions whose operand format is reg1 or reg2.
In this addressing mode, the 5 or 16 bits of data constituting the operation code are handled as an operand. This
addressing is used by those instructions whose operand format is imm5 or imm16.
In this addressing mode, when the memory area containing the operand is accessed, its address is determined
from the sum of the contents of the general-purpose register designated by the address designation code and
the 16-bit displacement in the instruction. This addressing is used by those instructions having an operand format
of disp16[reg1].
