Figure 6. Timing Diagram—Standard SDRAM Memory Write Timing
3.3.5.3
Memory Interface Timing-DDR SDRAM Read Command
The SDRAM Memory Controller uses an internally skewed clock for reading DDR memory. The
programmable bits in the Reset Configuration Register used to account for unknown board delays are in
the CDM module. The internal read clock can be delayed up to 3 ns under worst operating conditions in
32 increments of 95 ps, (1.4 ns in 45 ps increments under best case operating conditions) by programming
the CDM Reset Configuration Register tap delay bits. Note: These bits in the CDM Reset Configuration
register are not ‘reset configured’ but have a hard coded reset value and are writable during operation.
