Read returns zero.
Measured value of the magnitude of the received signal's horizontal eye opening.
00 0000 = minimum
11 1111 = maximum
Read returns zero.
Programmable range will cover at least –12 to 12 ps. The transfer function from Reg-
ister 24 to the actual picoseconds of phase shift is highly variable.
Value is signed, in 2s complement format:
100 0001 < –12 ps
011 1111 > 12 ps
