8.10.2 MPR Register Address Definition
Table 6 provides an overview of the available data locations, how they are addressed by MR3 A[1:0]
during a MRS to MR3, and how their individual bits are mapped into the burst order bits during a Multi
Purpose Register Read.

Note: Burst order bit 0 is assigned to LSB and the burst order bit 7 is assigned to MSB of the selected MPR agent.
8.10.3 Relevant Timing Parameters
The following AC timing parameters are important for operating the Multi Purpose Register: t RP , t MRD ,
t MOD , and t MPRR . For more details refer to section 10.16 “ AC Characteristics ” for DDR3-1333 to
DDR3-1866 on page 138.
8.10.4 Protocol Example
Protocol Example (This is one example):
Read out pre-determined read-calibration pattern.
Description: Multiple reads from Multi Purpose Register, in order to do system level read timing
calibration based on pre-determined and standardized pattern.
Protocol Steps:
?
?
?
?
Precharge All.
Wait until t RP is satisfied.
Set MRS, ― MR3 A[2] = 1b ‖ and ― MR3 A[1:0] = 00b ‖ .
This redirects all subsequent reads and load pre-defined pattern into Multi Purpose Register.
Wait until t MRD and t MOD are satisfied (Multi Purpose Register is then ready to be read). During the
period MR3 A[2] =1, no data write operation is allowed.
