Sample Program for Figure 28 INS8048 Interface 9.1.2.4 Interfacing the Z-80 The Z-80 control bus is slightly different from that of the 8080. General RD and WR strobes are provided and separate memory request, MREQ, and I/O request, IORQ, signals are used which have to be combined with the generalized strobes to provide the equivalent 8080 signals. An advantage of operating the ADC in I/O space with the Z-80 is that the CPU will automatically insert one wait state (the RD and WR strobes are extended one clock period) to allow more time for the I/O devices to respond. Logic to map the ADC in I/O space is shown in Figure 30. 20 Submit Documentation Feedback Copyright © 2009–2015, Texas Instruments Incorporated Product Folder Links: ADC0801 ADC0802 ADC0803 ADC0804 ADC0805 |
