Revision 3.1
4.3.4 Cyclic Redundancy Codes
The Cyclic Redundancy Check (CRC) protects against transmission errors that may occur
on the iNAND bus. Detailed information and examples for CRC7 and CRC16 are provided
in Section 4.5 of the SDA Physical Layer Specification, Version 2.00.
4.3.5 Error Conditions
See Section 4.6 of the SDA Physical Layer Specification, Version 2.00.
4.3.6 Commands
See Section 4.7 of the SDA Physical Layer Specification, Version 2.00 for detailed
information about iNAND commands.
4.3.7 Card State Transition
The state transition is dependent on the received command. The transition is defined in
Section 4.8 of the SDA Physical Layer Specification, Version 2.00 along with responses
sent on the command line.
4.3.8 Timing Diagrams and Values
See Section 4.12 of the SDA Physical Layer Specification, Version 2.00.
4.3.9 Speed Class Specification
The speed class specification classifies card performance by speed class number and offers
the method to calculate performance. For more information, refer to Section 4.13 of the
SDA Physical Layer Specification, Version 2.00.
4.3.10 Erase Timeout Calculation
See Section 4.14 of the SDA Physical Layer Specification, Version 2.00.
