Calibration Code

Write-only

0Xff: Calibration command after initialization

0Xab: Long calibration

0x56: Short calibration

0Xc3: ZQ Reset

All others: Reserved

Notes:

Host processor shall not write MR10 with “Reserved” values.

LPDDR2 devices shall ignore calibration command, when a “Reserved” values is written into MR10.

See AC timing table for the calibration latency.

If ZQ is connected to VSS through RZQ, either the ZQ calibration function (see “MRW ZQ Calibration Command”) or default

calibration (through the ZQ RESET command) is supported. If ZQ is connected to VDDCA, the device operates with default

calibration, and ZQ calibration commands are ignored. In both cases, the ZQ connection must not change after power is

supplied to the device. Devices that do not support calibration ignore the ZQ calibration command.
