Errata Description
Description (added 7/14/99):
Applies
to Mask
2J26D
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).
