t
SCO frequency selected by SCR and CDIV pins.
t
All edges mentioned refer to SCP = 0. Invert SCO edges for SCP = 1.
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.
