Accumulation results during a window defined by W are stored in the
diagnosticstable.
The latest result can be read out for diagnostic purposes.

Data sampling
The I_LOW field in the Table 89 SPI-4 ingress configuration register
(Block_base 0x0300 + Register_offset 0x00) selects an operating mode
between 80 MHz and 200 MHz or between 200 MHz and 400 MHz.
Each lane is over-sampled by a factor of five. The over-sampled data is
generated by a locked tapped delay line and clocked in to a register at the clock
rate. The current samples c(n) and the previously generated samples provide
samplesfortheeyecomputation.Theoptimizedsamplingpointwillbeselected
based on the eye computation. The tap selector is updated if necessary at the
end of the eye pattern measurement interval. The tap selector moves no more
than one tap at a time as a result of the eye pattern measurement.
