Effective Address Calculation
The effective address is the sum of PC value and
the value that is obtained by doubling the sign-
extended 12-bit displacement (disp).
The effective address is the sum of PC value and
Rn.
The 20-bit immediate data (imm) for the MOVI20
instruction is sign-extended.
The 20-bit immediate data (imm) for the MOVI20S
instruction is shifted by eight bits to the left, the
upper bits are sign-extended, and the lower bits
are padded with zero.
Sign-extended
The 8-bit immediate data (imm) for the TST, AND,
OR, and XOR instructions is zero-extended.
The 8-bit immediate data (imm) for the MOV, ADD,
and CMP/EQ instructions is sign-extended.
The 8-bit immediate data (imm) for the TRAPA
instruction is zero-extended and then quadrupled.
The 3-bit immediate data (imm) for the BAND,
BOR, BXOR, BST, BLD, BSET, and BCLR
instructions indicates the target bit location.
