3.5 Serial RapidIO Signals
Refer to Chapter 16, Serial RapidIO
Controller for configuration information.
ECC_MDM
Output
ECC Data Output Mask
Masks ECC data bytes transferred during a burst write. These signals are used to
support sub-burst-size transactions (such as single-byte writes) on SDRAM in which all
transactions occur in multi-byte bursts.
ECC_MDQS
Input/Output
ECC Data Strobe
Strobe for ECC data capture. The signal is driven as an input by the DDR SRAM with
read data and driven by the DDR controller as an output with write data. The strobes
may be single-ended or differential.
ECC_MDQS
Input/Output
ECC DQS Complement
Complement strobe for byte-lane data capture. The signal is driven as an input by the
DDR SRAM with read data and driven by the DDR controller as an output with write
data. The strobes may be single-ended or differential.
MDIC[0–1]
Input/Output
Driver Impedance Calibration
These lines are used for automatic calibration of the DDR I/O.
MODT[0–1]
Output
On-Die Termination
Memory controller outputs for the ODT to the SDRAM. Each signal represents the
corresponding chip select.
