register is updated).
and the Reed-Solomon ECC calculation generates 80 bits of ECC for every 1 byte to 512
bytes of valid data.
This register is used to read the ECC calculated in this circuit.
When 0 is written to NDFMCR0<ECCE> after read/write ends, ECC is prepared in this
The Hamming ECC calculation generates 22 bits of ECC for every 256 bytes of valid data
Three 32-bit width registers are provided to store 80 bits.
The table below shows the format for storing ECC.
the NAND Flash ECC register is updated when NDFMCR0<ECCE> changes from 1 to 0. Also note that when
the ECC in the ECC generator is reset by NDFMCR0<ECCRST>, the contents of this register are not reset.
