Output Clock (CKo3) Frequency and Output Frame Pulse (FPo3) Pulse Cycle
Selection
Output Clock (CKo3) Polarity Selection
When this bit is low, the output clock CKo3 falling edge aligns with the frame
boundary. When this bit is high, the output clock CKo3 rising edge aligns with the
frame boundary.
Output Frame Pulse (FPo3) Polarity Selection
When this bit is low, the output frame pulse FPo3 has the negative frame pulse format.
When this bit is high, the output frame pulse FPo3 has the positive frame pulse format.
Output Frame Pulse (FPo3) Position
When this bit is low, FPo3 straddles frame boundary (as defined by ST-BUS).
When this bit is high, FPo3 starts from frame boundary (as defined by GCI-Bus).
Output Clock (CKo2) Polarity Selection
When this bit is low, the output clock CKo2 falling edge aligns with the frame
boundary. When this bit is high, the output clock CKo2 rising edge aligns with the
frame boundary.
Output Frame Pulse (FPo2) Polarity Selection
When this bit is low, the output frame pulse FPo2 has the negative frame pulse format.
When this bit is high, the output frame pulse FPo2 has the positive frame pulse format.
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).
