Reset Description
DDR2_BA 2-0
O/T
?
High-Z/
DDR2 Bank Address Input. Define which bank an ACTIVATE,
Driven low READ, WRITE, or PRECHARGE command is being applied. BA2–0
define which mode register including MR, EMR, EMR(2), and
EMR(3) is loaded during the LOAD MODE command.
DDR2_CAS
O/T
?
High-Z/
DDR2 Column Address Strobe. Connect to DDR2_CAS pin, in
Driven
high
conjunction with other DDR2 command pins, defines the operation for
the DDR2 to perform.
DDR2_CKE
O/T
?
High-Z/
DDR2 Clock Enable Output to DDR2. Active high signal. Connect to
Driven low DDR2 CKE signal.
DDR2_CS 3-0
O/T
?
High-Z/
DDR2 Chip S elect. Al l commands are masked when DDR2_CS 3-0 is
Driven

driven high. DDR2_CS 3-0 are decoded emory address lines. Each
DDR2_CS 3-0 lines select the corresponding bank.
DDR2_DATA 15-0
DDR2_DM 1-0

High-Z
High-Z/
DDR2 Data In/Out. Connect to corresponding DDR2_DATA pins.
DDR2 Input Data Mask. Mask for the DDR2 write data if driven high.
Driven
high
Sampled on both edges of DDR2_DQS at DDR2 side. DM0 corresponds
to DDR2_DATA 7–0 and DM1 corresponds to DDR2_DATA 15–8.
DDR2_DQS 1-0
I/O/T (Differential)
?
High-Z
Data Strobe. Output with Write Data. Input with Read Data. DQS0
DDR2_DQS 1-0
corresponds to DDR2_DATA 7–0 and DQS1 corresponds to DDR2_DATA
15–8.
DDR2_RAS
O/T
?
High-Z/
DDR2 Row Address Strobe. Connect to DDR2_RAS pin, in conjunction
Driven
high
with other DDR2 command pins, defines the operation for the DDR2 to
perform.
DDR2_WE
O/T
?
High-Z/
DDR2 Write Enable. Connect to DDR2_WE pin, in conjunction with
Driven
high
other DDR2 command pins, defines the operation for the DDR2 to
perform
DDR2_CLK0 ,
O/T (Differential)
?
High-Z/
DDR2 Clock. Free running, minimum frequency not guaranteed during
DDR2_CLK0,
DDR2_CLK1 ,
DDR2_CLK1
driven low reset.
DDR2_ODT
O/T
?
High-Z/
DDR2 On Die Termination. ODT pin when driven high (along with
Driven low other requirements) enables the DDR2 termination resistances.
AMI_MS 0–1
O/T
?
High-Z
Memory Select Lines 0–1. These lines are asserted (low) as chip selects
for the corresponding banks of external memory on the AMI interface.
The MS 1-0 lines are decoded memory address lines that change at the
same time as the other address lines. When no external memory access
is occurring the MS 1-0 lines are inactive; they are active however when
a conditional memory access instruction is executed, whether or not
the condition is true.
The MS1 pin can be used in EPORT/FLASH boot mode. For more infor-
mation, see the ADSP-2146x SHARC Processor Hardware Reference.
