What is the smallest portion that can be changed at one time?
A. The smallest amount of configuration memory that can be written to or read from is a frame. A frame spans from the bottom of the device to the top of device, including the IOBs and CLBs, and contains a section of the data needed for each row. There are 48 frames per CLB column. Frame size is dependent of the device size and ranges from 384 bits for a XCV50 to 1248 bits for a XCV1000.
