2.3.3. Combining Pin and Byte Swizzling
Example : Combining Pin and Byte Swizzling
This example combines the two previous examples, entering the following swizzle parameters:
- PIN_SWIZZLE_CH0_DQS0=3,1,2,0,4,7,5,6;
- PIN_SWIZZLE_CH0_DQS2=16,23,18,19,20,21,22,17;
- BYTE_SWIZZLE_CH0=2,X,X,X,1,0,3,X;
The following table shows the resulting pin placement after DQ pin and byte swizzling.

Note:
When using the EMIF IP with 2 channels , the syntax for CH0 and CH1 must be the following:
- PIN_SWIZZLE_CH0_DQS0/ PIN_SWIZZLE_CH1_DQS0
- PIN_SWIZZLE_CH0_DQS2/ PIN_SWIZZLE_CH1_DQS2
- BYTE_SWIZZLE_CH0/ BYTE_SWIZZLE_CH1
