Microsemi ProprietaryUG0446 User Guide Revision 7.0
Used in the DDRIO calibration block as an override
to lock the codes during intermediate runs. When
the firmware receives CALIB_INTRPT, it may
choose to assert this signal by prior knowledge of
the traffic without going through the process of
putting the DDR into self refresh.
Indicates that rerun of the calibration state machine
is required in the DDRIO calibration block.
Indicates the DPC override NCODE from flash in
DDRIO calibration. This can also be overwritten
from the firmware.
Indicates the PC override PCODE from flash in the
DDRIO calibration block. This is also be overwritten
from the firmware.
Description
Software should not rely on the value of a reserved
bit. To provide compatibility with future products, the
value of a reserved bit should be preserved across a
read-modify-write operation.
