Explanation
SUMC
to SValue2 (if C = 0) and stores the result into the SValue1 register.
If the
effect is specified, the C flag is set (1) if the summation resulted in a signed overflow. The
result is written to SValue1 unless the
SUMNC
Instruction: Sum a signed value with another whose sign is inverted depending on !C.
SUMNC
Result: Sum of signed SValue1 and ±SValue2 is stored in SValue1.
Explanation

to –SValue2 (if C = 0) and stores the result into the SValue1 register.
If the
effect is specified, the C flag is set (1) if the summation resulted in a signed overflow. The
