Halfcarry is set on carry from the low order four bits.

To see how to compute it, let's take a look at the following table, which
|
|
shows the binary addition of two binary numbers:
|
|
|
|
A B A+B
|
|
-----------
|
|
0 0 0
|
|
0 1 1
|
|
1 0 1
|
|
1 1 0
|
|
|
|
Note that if only the lowest bit is used, then A+B, A-B and A^B yield the same
|
|
value. If we know A, B and the sum A+B+C, then C is easily derived:
|
|
C = A+B+C - A - B, that is
|
|
C = A+B+C ^ A ^ B.
|
|
|
|
For the halfcarry, A and B above are the fifth bit of a byte, which corresponds
|
|
to the value 0x10. So:
|
|
|
|
Halfcarry = ((accumulator+operand+halfcarry) ^ accumulator ^ operand) & 0x10
|
|
|
|
Note that masking off all bits but one is important because we have worked all
|
|
the math by using one bit only.
|
|
*/
|
|
if( (A ^ op ^ x) & 0x10 ) F |= Halfcarry;
|
|
|
|
/*
|
|
The overflow bit is set when the result is too large to fit into the destination
|
|
register, causing a change in the sign bit.
|
|
|
|
For a sum, we can only have overflow when adding two numbers that are both positive
|
|
or both negative. For example 0x5E + 0x4B (94 + 75) yields 0xA9 (169), which fits
|
|
into an 8-bit register only if it is interpreted as an unsigned number. If we
|
|
consider the result as a signed integer, then 0xA9 corresponds to decimal -87 and
|
|
we have overflow.
|
|
Note that if we add two signed numbers of opposite sign then we cannot overflow
|
|
the destination register, because the absolute value of the result will always fit
|
|
in 7 bits, leaving the most significant bit free for use as a sign bit.
|
|
|
|
We can code all the above concisely by noting that:
|
|
|
|
~(A ^ op) & 0x80
|
|
|
|
is true if and only if A and op have the same sign. Also:
|
|
|
|
(x ^ op) & 0x80
|
|
|
|
is true if and only if the sum of A and op has taken a sign opposite to that
|
|
of its operands.
|
|
|
|
Thus the expression:
|
|
|
|
~(A ^ op) & (x ^ op) & 0x80
|
|
|
|
reads "A has the same sign as op, and the opposite as x", where x is the sum of

A and op (and an optional carry).
