9.2.1
The DDR memory controller supports the following modes:
9.3
This section provides descriptions of the DDR memory controller’s external signals. It describes each
signal’s behavior when the signal is asserted or negated and when the signal is an input or an output.
9.3.1
Memory controller signals are grouped as follows:
Table 9-1
specification has a pinout diagram showing pin numbers. It also lists all electrical and mechanical
specifications.

Support for up to eight posted refreshes
Memory controller clock frequency of two times the SDRAM clock with support for sleep power
management
32-byte cache line wrap mode
Dynamic power management mode. The DDR memory controller can reduce power consumption
by negating the SDRAM CKE signal when no transactions are pending to the SDRAM.
Auto-precharge mode. Clearing DDR_SDRAM_INTERVAL[BSTOPRE] causes the memory
controller to issue an auto-precharge command with every read or write transaction.
Auto-precharge mode can be enabled for separate chip selects by setting
CSn_CONFIG[AP_n_EN].
