Configures the tFAW and tMAWi timing parameters.
The t_act_window_now register characteristics are:
- Usage constraints
Can be read from when in ALL states. Cannot be written to and only updated when in CONFIG, LOW-POWER or PAUSED states.
There is only one DMC configuration.
The following figure shows the bit assignments.
Figure 3-282 t_act_window_now register bit assignments
The following shows the bit assignments.
- [31:26] Reserved_2
- [25:16] t_mawi_now
Sets the value of the average delay required between ACTIVATE commands to the same row to not violate tMAC in tMAW. Must be programmed to (tMAW/(tMAC/2)).
- [15:6] Reserved_1
- [5:0] t_faw_now
The DMC does not issue more than 4 ACTIVATE commands within a rolling tFAW window. The supported range for this bitfield is 8-63.
