(CONTINUED)
PCBE0
Y3
I/O/Z
PCI command/byte enable 0 (I/O/Z). When PCI is disabled (PCI_EN = 0), this pin is tied-off.
For the C6414 device this pin is “Reserved (leave unconnected, do not connect to power or
ground).”
XSP_CS

O
IPD
PCI serial interface chip select (O). When PCI is disabled (PCI_EN = 0), this pin is tied-off.
For the C6414 device this pin is “Reserved (leave unconnected, do not connect to power or
ground).”

IPU
McBSP2 receive data (I) [default] or PCI serial interface data in (I). In PCI mode, this pin is
connected to the output data pin of the serial PROM.
DX2/XSP_DO§

IPU
McBSP2 transmit data (O/Z) [default] or PCI serial interface data out (O). In PCI mode, this pin
is connected to the input data pin of the serial PROM.
GP15/PRST§
J8
General-purpose input/output (GPIO) 15 pin (I/O/Z) or PCI reset (I). No function at default.

EMIFA peripheral data transfer, allows direct transfer between external peripherals
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.
|| 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 signal
whereas 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 of
discussion, 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.
