Figure 7-17 FSCD Timing
Note: 1) The only way to use FSCD is when DCL and FSC are both outputs.

8 Mbit/s) and in active mode (refer to Table 7-13, Table 7-14, Table 7-15 and
Table 7-16). When FSC is configured as input, FSCD is in tri-state. If FSC is
configured as output and the PEDIU is in idle mode or is not in work mode 2,
3 or 4, FSCD will be driven by constant ‘0’
