AXI4-Lite Slave Control/Status Register Map Detailed Descriptions
ECC_STATUS
This register holds information on the occurrence of correctable and uncorrectable errors.
The status bits are independently set to 1 for the first occurrence of each error type. The
status bits are cleared by writing a 1 to the corresponding bit position; that is, the status bits
can only be cleared to 0 and not set to 1 using a register write. The ECC Status register
operates independently of the ECC Enable Interrupt register.
ECC_EN_IRQ
This register determines if the values of the CE_STATUS and UE_STATUS bits in the ECC
Status Register assert the Interrupt output signal (ECC_Interrupt). If both CE_EN_IRQ and

Notes:
1. Data bits 64–127 are only enabled if the DQ width is 144 bits.
2. Reporting address bits 63–32 are only available if the address map is > 32 bits.
3. FI_D* and FI_ECC* are only enabled if ECC_TEST parameter has been set to 1.
