DESCRIPTION
HEO value, requires CDR to be locked for valid measurement
VEO value, requires CDR to be locked for valid measurement
Use these bits to read back the EOM voltage range setting:
00: ±100 mV
01: ±200 mV
10: ±300 mV
11: ±400 mV
Controls the amount of time the EOM samples each point in the
eye for. The total counter bit width is 16-bits. This register is the
upper 8-bits. The counter counts in 32-bit words. Therefore, the
total number of bits is 32 times this value
These bits set the number of hits for a particular phase and
voltage location in the EOM before the EOM will indicate a hit has
occurred. This filtering only affects the HEO measurement. Filter
threshold ranges from 0 to 15 hits.
