Must be zero for normal operation.
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.
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 ½ CLK cycle.
The binary value expressed in these bits refers to the measured input offset value. These bits are rest to
zero when the SFE bit of the IMS register changes from 1 to 0. (FD10 – MSB, FD0 – LSB)
