FPO2POS
Output Frame Pulse (FPo2) Position
When this bit is low, FPo2 straddles frame boundary (as defined by ST-BUS).
When this bit is high, FPo2 starts from frame boundary (as defined by GCI-Bus).

CKO1P
Output Clock (CKo1) Polarity Selection
When this bit is low, the output clock CKo1 falling edge aligns with the frame
boundary. When this bit is high, the output clock CKo1 rising edge aligns with the
frame boundary.

FPO1POS
CKO0P
Output Frame Pulse (FPo1) Polarity Selection
When this bit is low, the output frame pulse FPo1 has the negative frame pulse format.
When this bit is high, the output frame pulse FPo1 has the positive frame pulse format.
Output Frame Pulse (FPo1) Position
When this bit is low, FPo1 straddles frame boundary (as defined by ST-BUS).
When this bit is high, FPo1 starts from frame boundary (as defined by GCI-Bus).
Output Clock (CKo0) Polarity Selection
When this bit is low, the output clock CKo0 falling edge aligns with the frame
boundary. When this bit is high, the output clock CKo0 rising edge aligns with the
frame boundary.

FPO0P
Output Frame Pulse (FPo0) Polarity Selection
When this bit is low, the output frame pulse FPo0 has the negative frame pulse format.
When this bit is high, the output frame pulse FPo0 has the positive frame pulse format.
FPO0POS
Output Frame Pulse (FPo0) Position
When this bit is low, FPo0 straddles frame boundary (as defined by ST-BUS).
When this bit is high, FPo0 starts from frame boundary (as defined by GCI-Bus).
Note: In Divided Slave modes, CKo3 - 1 cannot exceed frequency of CKi.
Note: CKo[5:4] are available in Master mode or in Slave mode with SLV_DPLLEN set.
