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
