For proper device operation, the BEA8 and BEA9 pins must be externally pulled up

with a 1-k

Ω resistor.

BEA1

A14

with a 1-k

Ω resistor.

For more details, see the Device Configurations section of this data sheet.

† 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.

k To maintain signal integrity for the EMIF signals, serial termination resistors should be inserted into all EMIF output signal lines.
