376 | Note that if only the lowest bit is used, then A+B, A-B and A^B yield the same | ||

378 | C = A+B+C - A - B, that is | ||
379 | C = A+B+C ^ A ^ B. | ||
380 | |||
381 | For the halfcarry, A and B above are the fifth bit of a byte, which corresponds | ||
382 | to the value 0x10. So: | ||

384 | Halfcarry = ((accumulator+operand+halfcarry) ^ accumulator ^ operand) & 0x10 | ||
385 | |||

392 | The overflow bit is set when the result is too large to fit into the destination | ||
393 | register, causing a change in the sign bit. | ||
394 | |||
395 | For a sum, we can only have overflow when adding two numbers that are both positive | ||
396 | or both negative. For example 0x5E + 0x4B (94 + 75) yields 0xA9 (169), which fits | ||
397 | into an 8-bit register only if it is interpreted as an unsigned number. If we | ||
398 | consider the result as a signed integer, then 0xA9 corresponds to decimal -87 and | ||
399 | we have overflow. | ||
400 | Note that if we add two signed numbers of opposite sign then we cannot overflow | ||
401 | the destination register, because the absolute value of the result will always fit | ||
402 | in 7 bits, leaving the most significant bit free for use as a sign bit. | ||
403 | |||

405 | |||
406 | ~(A ^ op) & 0x80 | ||

416 | |||
417 | ~(A ^ op) & (x ^ op) & 0x80 | ||
