Table 5–23. EPM240 Global Clock External I/O Timing Parameters
Table 5–24. EPM570 Global Clock External I/O Timing Parameters
The maximum frequency is limited by the I/O standard on the clock input pin. The 16-bit counter critical delay
performs faster than this global clock input pin maximum frequency.
