Figure 77. SDRAM Initialization Sequence
®
IXP1240 Network Processor
Notes:
1. Number of total initialization phase refresh cycles programmed as INIT_RFRSH value in register SDRAM_MEMINIT.
2. Burst length and CAS latency values programmed as BURSTL value in register SDRAM_MEMCTL0 emitted in this cycle.
3. INIT_DLY, tRSC values programmed into register SDRAM_MEMINIT.
4. tRP, tRC values programmed into register SDRAM_MEMCTL1
5. tRSC is minimum SDRAM programmable register value. In actual use, refresh cycles will not
occur immediately after tRSC cycles due to SDRAM unit internal pipeline delays.
