• CRC for single cycle data not present, CRC verification deactivated, SELCRCSx = 0b0.
• CRC polynomial(7:1) in SCRCPOLYx SELCRCSx = 0b1 not applicable with CRC poly-
nomial SCRCPOLYx(7:1) = 0x00.
• CRC polynomial 0x00 not applicable with SELCRCSx = 0b1.
• Other CRC lengths in SCRCLENx are not permitted with SELCRCSx = 0b0.

• SELCRCSx = 0b0
• CRC bit length in SCRCLENx = 0 .
• Extend the SCDLEN by the length of the present CRC that is subject to be ignored.
A CRC polynomial SCRCPOLYx = 0x00 is not applicable with SELCRCSx = 0b1.
