Synch. Clk
This is a 5-V, bi-directional pad that has a fast mode provision like the QSMCM pads.
The input path is always synchronous. The receiver has hysteresis in order to mini-
mize the effect of noise on the pins. In addition, the receiver has a digital filter (some-
what like the sequencer for the EPEE pad) to check for a state on the pin for a
particular number of clocks. The pad also has a pull-up device. Depending on the reset
state (see
