WebTo verify the readback data stream, compare it to the RBD golden readback file and masking readback bits with the MSD file. This approach is simple because there is a 1:1 correspondence between the start of the readback data stream and the start of the RBD and MSD files, making the task of aligning readback, mask, and expected data easier. WebFor more information, see "Readback" on page 23. ConfigRate The ConfigRate is the internally generated frequency of CCLK in Master Serial mode. The initial frequency is 2.5 MHz. The CCLK changes to the selected frequency after the first 60 bytes of the bitstream have been loaded. For details, see "Bitstream Format" on page 14. It
