Bits 21:18 – TITMSRST[3:0] ITM Soft Reset Time

Number of configuration clock (MCK2) cycles during which the ITM soft reset pin must remain asserted when the soft reset is applied to the ITMs. This must correspond to a value that is equal to or more than 8 PLLDDR clock cycles.

Bits 17:6 – TDLLLOCK[11:0] DLL Lock Time

Number of configuration clock (MCK2) cycles for the DLL to stabilize and lock, i.e. number of clock cycles from when the DLL reset pin is de-asserted to when the DLL has locked and is ready for use. Default value corresponds to 5.12 µs at 533 MHz.

Bits 5:0 – TDLLSRST[5:0] DLL Soft Reset Time

Number of configuration clock (MCK2) cycles during which the DLL soft reset pin must remain asserted when the soft reset is triggered in DDR3PHY_PIR. This must correspond to a value that is equal to or more than 50 ns or 8 controller clock cycles, whichever is bigger. Default value corresponds to 50 ns at 533 MHz.
