Description
15 - 13
Unused
Must be zero for normal operation.
12
CFE
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. (FD10 = MSB, FD0 = LSB)
