Electrical Characteristics
Schmitt Trigger Input
Cyclone III devices support Schmitt trigger input on TDI , TMS , TCK , nSTATUS , nCONFIG ,
nCE , CONF_DONE , and DCLK pins. A Schmitt trigger feature introduces hysteresis to the
input signal for improved noise immunity, especially for signal with slow edge rate.
