Appendix B: Register Details
Register reg_65 Details
Reset Value 0x00000000
Description Training control 3
Field Name Bits Type Reset Value Description
reg_phy_ctrl_slave_del
ay
19:18 rw 0x0 If reg_phy_rd_dqs_slave_force is 1, replace
delay/tap value for address/command timing
slave DLL with this value
reg_phy_dis_calib_rst 17 rw 0x0 Disable the dll_calib (internally generated) signal
from resetting the Read Capture FIFO pointers
and portions of phy_data.
Note: dll_calib is
(i) generated by dfi_ctrl_upd_req or
(ii) by the PHY when it detects that the clock
frequency variation has exceeded the bounds set
by reg_phy_dll_lock_diff or
(iii) periodically throughout the leveling process.
dll_calib will update the slave DL with
PVT-compensated values according to master
DLL outputs
reg_phy_use_rd_data_
eye_level
16 rw 0x0 Read Data Eye training control.
0: Use register programmed ratio values
1: Use ratio for delay line calculated by data eye
leveling
Note: This is a Synchronous dynamic signal that
requires timing closure
reg_phy_use_rd_dqs_g
ate_level
15 rw 0x0 Read DQS Gate training control.
0: Use register programmed ratio values
1: Use ratio for delay line calculated by DQS gate
leveling
Note: This is a Synchronous dynamic signal that
requires timing closure.
reg_phy_use_wr_level 14 rw 0x0 Write Leveling training control.
0: Use register programmed ratio values
1: Use ratio for delay line calculated by write
leveling
Note: This is a Synchronous dynamic signal that
requires timing closure.
reg_phy_dll_lock_diff 13:10 rw 0x0 The Maximum number of delay line taps
variation allowed while maintaining the master
DLL lock.
When the PHY is in locked state and the variation
on the clock exceeds the variation indicated by the
register, the lock signal is deasserted
