26.6.24.2.3 CHI LRAM Checkbits
The coding of the checkbits reported in ECC Error Report Code Register (FR_EERCR) for CHI LRAM
memory errors is shown in Table 26-133. This table shows the implemented Hamming code. If the error
injection was applied to distort the checkbits, then the distorted checkbits are reported.
