8-bit Receive Data Bus.
Using the Receive Data Bus, the UTOPIA Slave (on the rising edge of the URCLK) can receive
h 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.

Reserved (leave unconnected, do not connect to power or ground. If the signal must be
routed out from the device, the internal pull−up/down resistance should not be relied upon and
an external pull−up/down should be used).

IPD Reserved. This pin must be connected directly to VSS for proper device operation.
† _{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.)
hExternal 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.
