What is the Control Signal ?
External clock signal (EXTCLK0/EXTCLK1)
These signals input external pacer clocks. The maximum frequency is 10MHz.
When the external clock input is set as the clock source, pattern input or output occurs at the falling
edge of this signal.
tPWH : Clock pulse high width 50ns (Min.)
tPWL : Clock pulse low width 50ns (Min.)
