* 3 = undocumented, bit 3 of the result byte
* P = parity (set if the result byte has an even number of bits set) or overflow (set when crossing the boundary of the signed range); always specified
* n N = negative, set if the previous operation was a subtraction; always specified * cc C = carry, the theoretical bit 8 of the result byte
* 0 = always reset
* 1 = always set
* P = parity (only for the parity flag)
* V = overflow (only for the parity flag)
* nn A = Or OR with the respective bit of the accumulator* cc C = set if the counter (bc) is nonzero after decrementing
