DDR Memory Controller
9.6
System software must configure the DDR memory controller, using a memory polling algorithm at system
start-up, to correctly map the size of each bank in memory. Then, the DDR memory controller uses its bank
map to assert the appropriate MCSn signal for memory accesses according to the provided bank depths.
System software must also configure the DDR memory controller at system start-up to appropriately
multiplex the row and column address bits for each bank. Refer to row-address configuration in
Section 9.4.1.2, “Chip Select Configuration (CSn_CONFIG).”
these configuration bits.
At system reset, initialization software (boot code) must set up the programmable parameters in the
memory interface configuration registers. See
descriptions of the configuration registers. These parameters are shown in

The number of ECC errors has reached the
threshold specified in the ERR_SBE.
A multi-bit ECC error is detected during a read, or
read-modify-write memory operation.
Read, or write, address does not fall within the
address range of any of the memory banks.
