Field
Description
0 EDC: ECC Data Correction (Read/Clear)
EDC provides information on previous reads. If a ECC Single Error detection and correction occurred, the
EDC bit will be set to 1. This bit must then be cleared, or a reset must occur before this bit will return to a
0 state. This bit may not be set to 1 by the user.
In the event of a ECC Double Error detection, this bit will not be set.
If EDC is not set, or remains 0, this indicates that all previous reads (from the last reset, or clearing of
EDC) were not corrected through ECC.
Since this bit is an error flag, it must be cleared to 0 by writing 1 to the register location. A write of 0 will
have no effect.
The function of this bit is SoC dependent and it can be configured to be disabled.
0: Reads are occurring normally.
1: An ECC Single Error occurred and was corrected during a previous read.
1:4 Reserved (Read Only)
Write these bits has no effect and read these bits always outputs 0.
5:7 SIZE2-0: array space SIZE 2-0 (Read Only)
110 64 KB array space size
8 Reserved (Read Only).
Write this bit has no effect and read this bit always outputs 0.
