摘要：
A study has been carried out to specify the undefined flag bits, D3 and D5, of the Z80 microprocessor. The set-reset conditions for D3 and D5 were observed experimentally with 50 different data sets under various instructions. Conclusions are drawn from the results of these tests about the set-reset conditions of the unspecified flag bits.
