Bits 26:17 – TDINIT3[9:0] DRAM Initialization Time 3

DRAM initialization time corresponding to the following:

LPDDR2 = Time from DDR_ZQ initialization command to first command (1 µs)

LPDDR3 = Time from DDR_ZQ initialization command to first command (1 µs)

Default value corresponds to the LPDDR2/3 1 µs at 533 MHz.

Bits 16:0 – TDINIT2[16:0] DRAM Initialization Time 2

DRAM initialization time corresponding to the following:

DDR3 = Reset low time (200 µs on power-up or 100 ns after power-up)

LPDDR2 = Time from reset command to end of auto-initialization (11 µs)

LPDDR3 = Time from reset command to end of auto-initialization (11 µs)

Default value corresponds to DDR3 200 µs at 533 MHz.
