ECCCLR (DDRC) Register Bit-Field Summary

Field NameBitsTypeReset ValueDescription
ecc_clr_uncorr_err_cnt 3wtcReadable, write a 1 to clear0x0Setting this register bit to 1 clears the currently stored uncorrected ECC error count. The ECCSTAT.ecc_uncorr_err_cnt register is cleared by this operation. When the clear operation is complete, the DDRC automatically clears this bit.
ecc_clr_corr_err_cnt 2wtcReadable, write a 1 to clear0x0Setting this register bit to 1 clears the currently stored corrected ECC error count. The ECCERRCNT.ecc_corr_err_cnt register is cleared by this operation. When the clear operation is complete, the DDRC automatically clears this bit.
ecc_clr_uncorr_err 1rwNormal read/write0x0Setting this register bit to 1 clears the currently starred corrected ECC error.The ECCSTAT.ecc corrected err, ADVECCSTAT.advecc_corrected_err, ADVECCSTAT.advecc_num_err_symbol, ADVECCSTAT.advecc_err_symbol_pos, ADVECCSTAT.advecc_err_symbol_bits,ECCCSYNO,ECCCSYN1,ECCCSYN2,
ECCBITMASKO,ECCBITMASK1 and ECCBITMASK2 registers are cleared by this operation.
uMCTL2 automatically clears this bit.
