MACH 4 Family

PAL Block Clock Generation
Each MACH 4 device has four clock pins that can also be used as inputs. These pins drive a
clock generator in each PAL block (Figure 14). The clock generator provides four clock signals
that can be used anywhere in the PAL block. These four PAL block clock signals can consist of
a large number of combinations of the true and complement edges of the global clock signals.
Table 12 lists the possible combinations.
Note:
1. M4(LV)-32/32 and M4(LV)-64/32 have only two clock pins, GCLK0 and GCLK1. GCLK2 is tied to GCLK0, and GCLK3 is tied to
GCLK1.
