The ispLSI 5000VE Family has four dedicated clock input
pins: CLK0 - CLK3. CLK0 input is used as the dedicated
master clock that has the lowest internal clock skew with
no clock inversion to maintain the fastest internal clock

speed. The clock inversion is available on the remaining
CLK1 - CLK3 signals. By sharing the pins with the I/O
pins, CLK2 and CLK3 can not only be inverted but are
also available for logic implementation through GRP
signal routing. Figure 5 shows these different clock
distribution options.
