Must be zero for normal operation.
Complete Frame Evaluation.
When CFE = 1, the frame evaluation is completed and bits FD10 to
FD0 bits contains a valid frame alignment offset. This bit is reset to zero, when SFE bit in the
IMS register is changed from 1 to 0.
11
FD11
Frame Delay Bit 11.
The falling edge of FE (or rising edge for GCI mode) is sampled during the
CLK-high phase (FD11 = 1) or during the CLK-low phase (FD11 = 0). This bit allows the
measurement resolution to 1/2 CLK cycle.
10-0
FD10 - 0
Frame Delay Bits.
The binary value expressed in these bits refers to the measured input offset
value. These bits are reset to zero when the SFE bit of the IMS register changes from 1 to 0.
