DSP56305 Errata  1996 - 2002 Motorola pg. 43 /ng/12/20/02
ED38
Description (added 7/14/99):
If Port A is used for external accesses, the BAT bits in the AAR3-0
registers must be initialized to the SRAM access type (i.e. BAT = 01)
or to the DRAM access type (i.e. BAT = 10). To ensure proper
operation of Port A, this initialization must occur even for an AAR
register that is not used during any Port A access. Note that at reset,
the BAT bits are initialized to 00.
Pertains to: DSP56300 Family Manual, Port A Chapter (Chapter 9
in Revision 2), description of the BAT[1 –0] bits in the AAR3 - AAR0
registers. Also pertains to the core chapter in device-specific user’s
manuals that include a description of the AAR3 - AAR0 registers
with bit definitions (usually Chapter 4).
