174 / 194 page  SCC Application Notes AMD 7–25 AS DS RD DTACK A B C PAL OUTPUTS: Figure 7–15. PAL Timing 7.5.4 The 68000 and Am8530H with Interrupts via a PAL Device This example shows how a Programmable Array Logic (PAL) device simplifies the task of interrupt generation compared to the MSI implementation. The block diagram for the in- terface via a PAL device is shown in Figure 7–14. The timing diagram (Figure 7–15) illus- trates the Interrupt Acknowledge cycle. As in the other designs, RD is generated during Interrupt Acknowledge to place the vector on the bus. The timing during register programming is not shown. The PAL device allows selection of one or two Wait States by making W0 High or Low respectively. The table below shows the appropriate number of Wait Sates as a function of CPU speed. CPU Speed Wait States 4 MHz 1 6 MHz 2 8 MHz 2 10 MHz 2 PAL device equations are shown in Figure 7–16. |
