Must be zero for normal operation.
12
CFE
When CFE = 1, the frame evaluation is completed and bits FD10 to FD0 bits contains a valid frame alignment
(Complete Frame Evaluation)
offset. This bit is reset to zero, when SFE bit in the IMS register is changed from 1 to 0.
11
FD11
The falling edge of FE (or rising edge for GCI mode) is sampled during the CLK-high phase (FD11 = 1)
(Frame Delay Bit 11)
or during the CLK-low phase (FD11 = 0). This bit allows the measurement resolution to CLK cycle.
10-0
FD10-0
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)
Read/Write Address:
02H,
Reset Value:
