ADDX
Add Extended
Description
Add the contents of data register D[a] to the contents of either data register D[b] (instruction format RR) or const9
(instruction format RC) and put the result in data register D[c]. The operands are treated as 32-bit signed integers.
The const9 value is sign-extended before the addition is performed. The PSW carry bit is set to the value of the
ALU carry out.
ADDXD[c], D[a], const9 (RC)
result = D[a] + sign_ext(const9);
D[c] = result[31:0];
carry_out = carry(D[a],sign_ext(const9),0);
ADDXD[c], D[a], D[b] (RR)
result = D[a] + D[b];
D[c] = result[31:0];
carry_out = carry(D[a],D[b],0);
