Table 26. Configuration Frame Format and Contents
Note: For slave parallel mode, the byte containing the preamble must be 11110010. The number of leading header dummy bits must be
(n
*
8) + 4, where n s any nonnegative integer and the number of trailing dummy bits must be (n
*
8), where n s any positive integer.
The number of stop bits/frame for slave parallel mode must be (x
*
8), where x is a positive integer. Note also that the bit stream
generator tool supplies a bit stream that is compatible with all configuration modes, including slave parallel mode.
