ADD
Operation
RS1 + RS2
RD + IMM16 ⇒ RD (translates to ADDL RD, #IMM16[7:0]; ADDH RD, #IMM16[15:8])
Performs a 16 bit addition and stores the result in the destination register RD.

Set if bit 15 of the result is set; cleared otherwise.
Set if the result is $0000; cleared otherwise.
Set if a two´s complement overflow resulted from the operation; cleared otherwise.
RS1[15] & RS2[15] & RD[15]
Refer to ADDH instruction for #IMM16 operations.
Set if there is a carry from bit 15 of the result; cleared otherwise.
RS1[15] & RS2[15] | RS1[15] & RD[15]
Refer to ADDH instruction for #IMM16 operations.

When using immediate addressing mode (ADD RD, #IMM16), the V-flag
and the C-Flag of the first instruction (ADDL RD, #IMM16[7:0]) are not
considered by the second instruction (ADDH RD, #IMM16[15:8]).
⇒ Don’t rely on the V-Flag if RD + IMM16[7:0] ≥ 2
⇒ Don’t rely on the C-Flag if RD + IMM16[7:0] ≥ 2
