GCI-Bus Selection for FPo0
When this bit is low, FPo0 is set for ST-BUS mode.
When this bit is high, FPo0 is set for GCI-Bus mode.
Frame Pulse Polarity Selection for FPo0
When this bit is low, FPo0 is set for active high.
When this bit is high, FPo0 is set for active low.
Clock Polarity Selection for CKo0
When this bit is low, CKo0 is set for the positive clock edge.
When this bit is high, CKo0 is set for the negative clock edge.
Output Clock Rate for CKo0 and FPo0
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.
