Frame Pulse Polarity Selection for FPo1
When this bit is low, FPo1 is set for active high.
When this bit is high, FPo1 is set for active low.
Clock Polarity Selection for CKo1
When this bit is low, CKo1 is set for the positive clock edge.
When this bit is high, CKo1 is set for the negative clock edge.
Output Clock Rate for CKo1 and FPo1
The output clock rate can not exceed the selected clock source rate. All rates are avail-
able when the internal system clock is selected as clock source.
Output Clock Source for CKo1 and FPo1
GCI-Bus Selection for FPo0
