Zero-extend n to word length.
Sign-extend n to word length.
Read data of size "b" from address "a".
Write data "b" of size "c" to address "a".
Read bit "b" of address "a".
Write "c" in bit "b" of address "a".
Perform saturation processing of n (n is 2's complement).
If n is a computation result and n ≥ 7FFFFFFFH, make n = 7FFFFFFFH.
If n is a computation result and n ≤ 80000000H, make n = 80000000H.
