1 tICLK = 1/fICLK.

2 SCO frequency selected by SCR and CDIV pins.

3 tSCO = t1 + t2.

4 All edges mentioned refer to SCP = 0. Invert SCO edges for SCP = 1.

5 In decimate × 32 mode, this time specification applies only when CDIV = 0 and SCR =1. For all other combinations of CDIV and SCR in decimate × 32 mode, the FSO

signal is constantly logic low.
