AECLKIN
J19
I
IPD
EMIFA external input clock. The EMIFA input clock (AECLKIN, CPU/4 clock, or CPU/6 clock)
is selected at reset via the pullup/pulldown resistors on the BEA[17:16] pins.
AECLKIN is the default for the EMIFA input clock.
AECLKOUT2
K18
O/Z
IPD
EMIFA output clock 2. Programmable to be EMIFA input clock (AECLKIN, CPU/4 clock, or
CPU/6 clock) frequency divided-by-1, -2, or -4.
AECLKOUT1

IPD
EMIFA output clock 1 [at EMIFA input clock (AECLKIN, CPU/4 clock, or CPU/6 clock)
frequency].
AARE/

O/Z
IPU
EMIFA asynchronous memory read-enable/SDRAM column-address strobe/programmable
synchronous interface-address strobe or read-enable
For programmable synchronous interface, the RENEN field in the CE Space Secondary
Control Register (CExSEC) selects between ASADS and ASRE:
If RENEN = 0, then the ASADS/ASRE signal functions as the ASADS signal.
If RENEN = 1, then the ASADS/ASRE signal functions as the ASRE signal.

ASDCKE
K21

IPU
EMIFA SDRAM clock-enable (used for self-refresh mode). [EMIFA module only.]
If SDRAM is not in system, ASDCKE can be used as a general-purpose output.

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