ORCA Series 2 FPGAs
Configuration Data Format (continued)
The data frames for all the Series 2 series devices are given in Table 8. An alignment field is required in the slave
parallel mode for the uncompressed format. The alignment field (shown by [A]) is a series of 0s: five for the
OR2C06A/OR2T06A, OR2C10A/OR2T10A, OR2C15A/OR2T15A/OR2T15B, and OR2C26A/OR2T26A; three for
the OR2C40A/OR2T40A/OR2T40B; and one for the OR2C04A/OR2T04A, OR2C08A/OR2T08A, and OR2C12A/
OR2T12A. The alignment field is not required in any other mode.
