7.1
The input bit delay programming feature provides users with the flexibility of handling different wire delays when
designing with source streams for different devices.
By default, all input streams have zero bit delay, such that bit 7 is the first bit that appears after the input frame
boundary (assuming ST-BUS formatting). The input delay is enabled by STIN[n]BD2-0 (bits 8 - 6) in the Stream
Input Control Register 0 - 31 (SICR0 - 31) as described in Table 24 on page 50. The input bit delay can range from
0 to 7 bits.
