Signals/Connections
1.4 External Memory Expansion Port (Port A)
Note:
When the DSP56321 enters a low-power standby mode (stop or wait), it releases bus mastership and tri-
states the relevant Port A signals: A[0–17], D[0–23], AA[0–3], RD, WR, BB.

Tri-stated
Address Bus—When the DSP is the bus master, A[0–17] are active-high
outputs that specify the address for external program and data memory
accesses. Otherwise, the signals are tri-stated. To minimize power dissipation,
A[0–17] do not change state when external memory spaces are not being
accessed.

Data Bus—When the DSP is the bus master, D[0–23] are
active-high, bidirectional input/outputs that provide the
bidirectional data bus for external program and data
memory accesses. Otherwise, D[0–23] drivers are tri-
stated. If the last state is output, these lines have weak
keepers to maintain the last output state if all drivers are tri-
stated.

Signal Description
AA[0–3]
Output
Tri-stated
Address Attribute—When defined as AA, these signals can be used as chip
selects or additional address lines. The default use defines a priority scheme
under which only one AA signal can be asserted at a time. Setting the AA priority
disable (APD) bit (Bit 14) of the Operating Mode Register, the priority
mechanism is disabled and the lines can be used together as four external lines
that can be decoded externally into 16 chip select signals.
RD
Output
Tri-stated
Read Enable—When the DSP is the bus master, RD is an active-low output that
is asserted to read external memory on the data bus (D[0–23]). Otherwise, RD is
tri-stated.
WR
Output
Tri-stated
Write Enable—When the DSP is the bus master, WR is an active-low output
that is asserted to write external memory on the data bus (D[0–23]). Otherwise,
the signals are tri-stated.
