This register configures and reports the status of the various internal operations
inside RTOP.
BUSY:
The BUSY bit indicates the status of the transfer of BIP and FEBE counts
from the counters to the holding registers. BUSY is set high on the rising
edge of the LCLK input or on a write access to any of the BIP or FEBE
counters. BUSY is set low when all the counters values have been
transferred to holding registers. The elapsed time shall be less than 10 µs.
BLKFEBE:
The block FEBE accumulation control bit selects between counting of FEBEs
in the incoming TU3 stream on a block or bit basis. When BLKFEBE is set
high, FEBE count codes in the range of 1 to 8 are accumulated on a block
basis as a single FEBE event. All other codes are counted zero events.
When BLKFEBE is set low, FEBE count codes in the range of 1 to 8 are
accumulated on a bit basis as a up to 8 FEBE events. All other codes are
counted zero events.
Reserved:
The Reserved bits must be written with a logic 0 for proper operation of the
TUPP-PLUS.
