8-bit Receive Data Bus.
Using the Receive Data Bus, the UTOPIA Slave (on the rising edge of the URCLK) can receive
the 8-bit ATM cell data from the Master ATM Controller.
When the UTOPIA peripheral is disabled (UTOPIA_EN [BEA11 pin] = 0), these pins are tied-
off.

‡
I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground
IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-kΩ IPD or IPU resistor. To pull up a signal to the opposite
supply rail, a 1-kΩ resistor should be used.)
ꢂ External pulldowns required: If UTOPIA is selected (BEA11 = 1) and these pins are connected to other devices, then a 10-kΩ resistor must be
used to externally pull down each of these pins. If these pins are “no connects”, then only UXCLK and URCLK need to be pulled down and other
pulldowns are not necessary.
ΨThe C6414T device does not support the UTOPIA peripheral; therefore, these standalone UTOPIA pins are Reserved (leave unconnected, do
not connect to power or ground) with the exception of UXCLK and URCLK which should be connected to a 10-kΩ pulldown resistor (see the
square [ꢂ ] footnote).
