The C6414 device does not support the PCI and UTOPIA peripherals; for proper device operation, do not oppose the internal pulldowns (IPDs) on the BEA13 and BEA11 pins.Also for proper C6414 device operation, Also for proper C6414 device operation do not oppose the IPDs on the BEA7, BEA8, oppose the IPDs on the BEA7 BEA8and BEA9 pins.
For proper C6415 device operation, the BEA7 pin must be externally pulled up with a1-k? resistor.
For proper C6416 device operation, the BEA8 and BEA9 pins must be externally pulledup with a 1-k? ? resistor.For more details, see the Device Configurations section of this data sheet.
IPD
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 oppositesupply rail, a 1-k? resistor should be used.)
||These C64x? devices have two EMIFs (64-bit EMIFA and 16-bit EMIFB). The prefix “A” in front of a signal name indicates it is an EMIFA signalwhereas a prefix “B” in front of a signal name indicates it is an EMIFB signal. Throughout the rest of this document, in generic EMIF areas ofdiscussion, the prefix “A” or “B” may be omitted from the signal name.
kTo maintain signal integrity for the EMIF signals, serial termination resistors should be inserted into all EMIF output signal lines.

McBSP2 enable pin. This pin works in conjunction with the PCI_EN pin to enable/disable otherperipherals (for more details, see the Device Configurations section of this data sheet).McBSP2 external clock source (CLKS2) [input only] [default] or this pin can also be programmed as a GPIO 8 pin (I/O/Z).
McBSP2 receive clock. When McBSP2 is disabled (PCI_EN = 1 and MCBSP2_EN pin = 0),this pin is tied-off.
McBSP2 transmit clock (I/O/Z) [default] or PCI serial interface clock (O).
McBSP2 receive data (I) [default] or PCI serial interface data in (I). In PCI mode, this pin isconnected to the output data pin of the serial PROM.
McBSP2 transmit data (O/Z) [default] or PCI serial interface data out (O). In PCI mode, this pinis connected to the input data pin of the serial PROM.
McBSP2 receive frame sync. When McBSP2 is disabled (PCI_EN = 1 and MCBSP2_EN pin = 0), this pin is tied-off.
McBSP2 transmit frame sync. When McBSP2 is disabled (PCI_EN = 1 and MCBSP2_EN pin = 0), this pin is tied-off.

§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 except CLKS2/GP8 are standaloneperipheral functions for this device.
