26.5.2. Register Descriptions

Table 290.  ECC Error Status FIFO Level Register (ECC_STATUS_FIFO_LVL)
Bit Fields Access Modified WriteValues Default Value Description
3131 eccfifo_overflow read-write writeToClear 0x0 ECC_STATUS_FIFO overflow error status. The maximum depth of ECC_STATUS_FIFO is 512.
Note: Writing to this field to clears the content of the field to 0.
[30:9] Reserved N/A 0x0 Reserved
[8:0] eccfifo_lvl read-only 0x0 Shows the current number of words stored in ECC_STATUS_FIFO.
Note:
When ECC_STATUS_FIFO is full, it will roll over to 0. The maximum depth of ECC_STATUS_FIFO is 512.
Table 291.  RAM address of ECC error status FIFO (ECC_ERR_ADDR_FIFO)The depth of ECC_ERR_ADDR_FIFO is 512.
Bit Fields Access Default Value Description
[31:26] Reserved N/A 0x0 Reserved
[25:0] ecc_err_addr read-only 0x0 The ECC_ERR_ADDR_FIFO holds the RAM’s read address(word-addressing) that has an ECC status of correctable or uncorrectable error.
Table 292.  ECC Error Status FIFO (ECC_STATUS_FIFO)The ECC_STATUS_FIFO holds the ECC status of correctable or uncorrectable error of the output data of memory.
Bit Fields Access Default Value Description
31:17 Reserved read-only 0x0 Reserved
16 RAM0_uncorrectable_ecc_err Holds the uncorrectable ECC error status of RAM 0
15:1 Reserved Reserved
0 RAM0_correctable_ecc_err Holds the correctable ECC error status of RAM 0
Table 293.  Control Register (CONTROL)
Bit Fields Access Default Value Description
[31:3] Reserved N/A 0x0 Reserved
232 eccencbypass_ena read-write 0x0 ECC Encoder Bypass feature is disabled by default. Write 1 to enable ECC Encoder Bypass feature.
1 pop_eccfifo read-write 0x0

Enabled to pop the next data from ECC_ERR_ADDR_FIFO and ECC_STATUS_FIFO.

This field will automatically reset to 0 after one data is pop out from the FIFO.

0 csr_soft_rst read-write 0x0

Enable soft reset to reset eccfifo_overflow status, ECC_ERR_ADDR_FIFO, ECC_STATUS_FIFO and parity_RAM0 registers.

This field will automatically reset to 0 after 8 clock cycles.

Table 294.  ECC parity input to RAM 0 register (PARITY_RAM0)Only applicable if parameter Enable ECC Encoder Bypass is enabled
Bit Fields Access Default Value Description
[31:8] Reserved N/A 0x0 Reserved
[7:0] parity_RAM0 read-write 0x0 8-bit parity input to RAM 0 when ECC Encoder Bypass is enabled.
31 Sticky bits
32 Only applicable if parameter Enable ECC Encoder Bypass is enabled
