CONFIGURATION SLAVE

Slave Configuration CRC Verification:

• 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.

32

STATUS INFORMATION 1

Bit address of nDELAYERR 0xF0 updated to 5

APPLICATION DESIGN

TRANSFER FROM iC-MB3

TSSOP24 TO iC-MB4 TSSOP24

Disabeling SCD CRC verification To deactivate the SCD CRC verification select:

• 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.
