External Crystal.
If a 25 or 27 MHz crystal is used as the device frequency reference, connect it across
XA and XB. If an input clock is used on pin 4, this pin should be tied to GND.
External Crystal.
If a 25 or 27 MHz crystal is used as the device frequency reference, connect it across
XA and XB. If an input clock is used on pin 4, this pin should be tied to GND.
Multi-Function Input.
This pin functions as a multi-function input pin. The pin function (OEB_all, OEB_01,
OEB_23, OEB_45, OEB_67, Frequency Select, or Reset) is user-selectable at time of
configuration using the ClockBuilder configuration utility.
Single-Ended Input Clock.
If a single-ended clock is used as the device frequency reference, connect it to this pin.
This pin functions as a high-impedance input for CMOS clock signals. The input should
be dc coupled. If a crystal is used as the device frequency reference, this pin should be
tied to GND.
