DESCRIPTION
EMIFA (64-bit) – ADDRESS
U23
V24
EMIFA external address (doubleword address)
V25
EMIFA address numbering for the DM643 device starts with AEA3 to maintain
signal name compatibility with other C64x™ devices (e.g., C6414, C6415, and
V26
C6416) [see the 64-bit EMIF addressing scheme in the TMS320C6000 DSP
V23
External Memory Interface (EMIF) Reference Guide (literature number
SPRU266)].
U24
U25
Note: If a configuration pin must be routed out from the device, the internal
pullup/pulldown (IPU/IPD) resistor should not be relied upon; TI recommends the
U26
use of an external pullup/pulldown resistor.
