LCV[15:0]
LCV[15:0] represents the number of DS3, E3, or J2 LCV errors that have been detected since
the last time the LCV counter was polled.
The counter (and all other counters in the PMON) is polled by writing to any of the PMON
register addresses (314H to 31FH) or to the S/UNI-JET Identification, Master Reset, and
Global Monitor Update Register (006H). Such a write transfers the internally accumulated
count to the LCV Error Count Registers and simultaneously resets the internal counter to
begin a new cycle of error accumulation. This transfer and reset is carried out in a manner
that coincident events are not lost. The transfer takes three RCLK cycles to complete.
