be pulled up.

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