Bits 26:19 – TDINIT1[7:0] DRAM Initialization Time 1
DDR3 = DDR_CKE high time to first command (tRFC +10 ns or 5 DDR_CLK periods, whichever value is larger)
DDR2 = DDR_CKE high time to first command (400 ns)
LPDDR2 = DDR_CKE low time with power and clock stable (100 ns)
LPDDR3 = CKE low time with power and clock stable (100 ns)
Default value corresponds to DDR3 360 ns at 533 MHz
Bits 18:0 – TDINIT0[18:0] DRAM Initialization Time 0
DDR3 = DDR_CKE low time with power and clock stable (500 µs)
DDR2 = DDR_CKE low time with power and clock stable (200 µs)
LPDDR2 = DDR_CKE high time to first command (200 µs)
LPDDR3 = DDR_CKE high time to first command (200 µs)
Default value corresponds to DDR3 500 µs at 533 MHz.
