MULTICHANNEL BUFFERED SERIAL PORT 2 (McBSP2)
McBSP2 enable pin. This pin works in conjunction with the PCI_EN pin to enable/disable other
peripherals (for more details, see the Device Configurations section of this data sheet).

XSP_CLK
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.
§
DR2/XSP_DI
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.

McBSP2 transmit frame sync. When McBSP2 is disabled (PCI_EN pin = 1 and MCBSP2_EN
pin = 0), this pin is 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.)
For the C6415T and C6416T devices, these pins are multiplexed pins. For more details, see the Device Configurations section of this data sheet.
The C6414T device does not support the PCI or UTOPIA peripherals; therefore, these muxed peripheral pins except CLKS2/GP8 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.
