BEA5

C16

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, do not oppose the IPDs on the BEA7, BEA8,

† 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-k

Ω 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 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.
