PHY Rollover_FIFO_EN
If this bit is logic 1, all per-PHY counts cause entries to be made in the Count Rollover FIFO
when their MSBs become logic 1. The MSB is reset to logic 0 when the FIFO entry is
successfully made. It is the responsibility of the management software either to ensure the
per-PHY counts are polled often enough to ensure they do not saturate, or to read the Count
Rollover FIFO. If this bit is logic 0, all per-PHY counts saturate at all ones.
Cnt_Rsvd_VCI_PTI
The Cnt_Rsvd_VCI_PTI controls the counting of F4 cells with VCI values of 0 or between 7
and 15, inclusive, and all cells with PTI = 7. If Cnt_Rsvd_VCI_PTI is a logic 1, these cells
are included in the count of Invalid VPI/VCI/PTI cells. If this bit is logic 0, only cells that
cannot be searched to a valid, active connection are counted in this count. In any event, cells
with an invalid VCI or PTI cause the INVALI interrupt to be asserted.
Cnt_Undef_OAM
If the Cnt_Undef_OAM bit is a logic 1, OAM cells with undefined OAM Type and Function
Type fields are accumulated in the per-PHY count of errored OAM/RM cells. If
Cnt_Undef_OAM is a logic 0, only OAM or RM cells with CRC-10 errors cause the per-
PHY errored OAM/RM cell count to increment. The OAMERRI interrupt is also asserted
when an OAM cell with an undefined OAM Type Function Type field is received.
Cnt_EFCI
If the Cnt_EFCI bit is logic 1, then with a PTI of 010 or 011 (which is the Explicit Forward
Congestion Indication) are accumulated in the per-PHY count of EFCI/Non-Zero GFC cells.
If this bit is logic 0, cells with EFCI are not accumulated.
