Figure 26-102. ECC Error Report and Injection Control Register (FR_EERICR)
This register configures the error injection and error reporting and provides the selector for the content of
the report registers.

Description
Register Update Busy— This field indicates the current state of the ECC configuration update
and controls the register write access condition IDL specified in “Section 26.5.2.2, Register write
access
0 ECC configuration is idle
1 ECC configuration is running
Error Report Select — This field selects the content of the ECC Error reporting registers.
00 show PE DRAM non-corrected error information
01 show PE DRAM corrected error information
10 show CHI LRAM non-corrected error information
11 show CHI LRAM corrected error information
Error Report Mode — This bit configures the type of data written into the internal error report
registers on the detection of a memory error.
0 store data and code as delivered by ecc decoding logic.
1 store data and code as read from the memory.
Error Injection Mode — This bit configures the ECC error injection mode.
0 use FR_EEIDR[DATA] and FR_EEICR[CODE] as XOR distortion pattern for error injection.
1 use FR_EEIDR[DATA] and FR_EEICR[CODE] as write value for error injection.
Error Injection Enable — This bit configures the ECC error injection on the memories.
0 Error injection disabled
1 Error injection enabled
Note: When the ECC functionality is required to be disabled (i.e.value of the FR_MCR[ECCE] is
0), Error Injection Enable bit FR_EERICR[EIE] should not be set to 1
