Notes:

“O” Stands for Optional, “M” for Mandatory

The Integrity CRC (Cycling Redundancy Check) field is used to verify that the contents of the parameters page were

transferred correctly to the host. Please refer to ONFI 1.0 specifications for details.

The CRC shall be calculated using the following 16-bit generator polynomial: G(X) = X16 + X15 +X2 + 1，This

polynomial in hex may be represented as 8005h.

3．The CRC value shall be initialized with a value of 4F4Eh before the calculation begins. There is no XOR applied to the

final CRC value after it is calculated. There is no reversal of the data bytes or the CRC calculated value.
