Which are the two additional registers of Z80?(a) Interrupt and NMI(b)

1.	Which are the two additional registers of Z80?(a) Interrupt and NMI(b) NMI and PSW(c) Interrupt vector and memory refresh(d) NMI and memory refreshThis question was addressed to me during an interview.Asked question is from Microprocessor of Embedded System topic in chapter Embedded System of Embedded Systems
Answer» Correct OPTION is (c) Interrupt vector and memory refresh The best I can explain: The Interrupt vector(IV) register is used in the interrupt handling. Mode 2 is used to point the REQUIRED software ROUTINE to process the interrupt. In mode 1, the interrupt vector is supplied via the external data bus.
