AT84CS001 Asynchronous Reset

When do I need to asynchronous reset the AT84CS001 1:2/4 10-bit 2.2 Gsps DMUX?

It is necessary to reset the AT84CS001 DMUX via the asynchronous reset (pin B17 of the EBGA240 package) after power up of the device and whenever one of the following function setting is modified:

- Ratio Selection (RS bit, pin L2 of the EBGA240 package);
- Input clock type selection (CLKTYPE bit, pin V18);
- Output clock type selection (DRTYPE bit, pin K1);
- Simultaneous or Staggered Output mode selection (STAGG bit, pin A17).
