DESCRIPTION
UNIVERSAL TEST AND OPERATIONS PHY INTERFACE FOR ASYNCHRONOUS TRANSFER MODE (ATM) [UTOPIA SLAVE]
[C6415 and C6416 devices only]
UTOPIA SLAVE (ATM CONTROLLER) TRANSMIT INTERFACE
UXCLKY
AB8
I
h
Source clock for UTOPIA transmit driven by Master ATM Controller.
When the UTOPIA peripheral is disabled (UTOPIA_EN [BEA11 pin] = 0), this pin is tied-off.
UXCLAVY
AA13
O/Z
Transmit cell available status output signal from UTOPIA Slave.
0
indicates a complete cell is NOT available for transmit
1
indicates a complete cell is available for transmit
When the UTOPIA peripheral is disabled (UTOPIA_EN [BEA11 pin] = 0), this pin is tied-off.
UXENBY
U13
I
UTOPIA transmit interface enable input signal. Asserted by the Master ATM Controller to indi-
cate that the UTOPIA Slave should put out on the Transmit Data Bus the first byte of valid data
and the UXSOC signal in the next clock cycle.
When the UTOPIA peripheral is disabled (UTOPIA_EN [BEA11 pin] = 0), this pin is tied-off.
UXSOCY
Y12
O/Z
Transmit Start-of-Cell signal. This signal is output by the UTOPIA Slave on the rising edge of
the UXCLK, indicating that the first valid byte of the cell is available on the 8-bit Transmit Data
Bus (UXDATA[7:0]).
When the UTOPIA peripheral is disabled (UTOPIA_EN [BEA11 pin] = 0), this pin is tied-off.

I/O/Z
McBSP1 [default] or UTOPIA transmit address pins
As UTOPIA transmit address pins UXADDR[4:0] (I), UTOPIA_EN (BEA11 pin) = 1:
5-bit Slave transmit address input pins driven by the Master ATM Controller to identify and
select one of the Slave devices (up to 31 possible) in the ATM System.
UXADDR0 pin is tied off when the UTOPIA peripheral is disabled [UTOPIA_EN
(BEA11 pin) = 0]
For the McBSP1 pin functions (UTOPIA_EN (BEA11 pin) = 0 [default]), see the MULTICHAN-
NEL BUFFERED SERIAL PORT 1 (McBSP1) section of this table.

As UTOPIA transmit address pins UXADDR[4:0] (I), UTOPIA_EN (BEA11 pin) = 1:

select one of the Slave devices (up to 31 possible) in the ATM System.

UXADDR0 pin is tied off when the UTOPIA peripheral is disabled [UTOPIA_EN

For the McBSP1 pin functions (UTOPIA_EN (BEA11 pin) = 0 [default]), see the MULTICHAN-
NEL BUFFERED SERIAL PORT 1 (McBSP1) section of this table.
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-k IPD or IPU resistor. To pull up a signal to the opposite
supply rail, a 1-k
resistor should be used.)
§ For the C6415 and C6416 devices, these pins are multiplexed pins. For more details, see the Device Configurations section of this data sheet.
The C6414 device does not support the PCI or UTOPIA peripherals; therefore, these MUXed peripheral pins are standalone peripheral functions
for this device.
hFor the C6415 and C6416 devices, external pulldowns required: If UTOPIA is selected (BEA11 = 1) and these pins are connected to other devices,
then a 10-k
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.
For the C6415 and C6416 devices, external pullups required: If UTOPIA is selected (BEA11 = 1) and these pins are connected to other devices,
then a 10-k
resistor must be used to externally pull up each of these pins. If these pins are “no connects”, then the pullups are not necessary.
ΨThe C6414 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-k
pulldown resistor (see the
square [
h] footnote).
