The input port can be enabled to remove (filter) Unassigned or Idle cells. If Unassigned or Idle Cell Filtering is
enabled, the device checks for and discards Unassigned or Idle cells. This function is programmed in the UTOPIA
Input Control (0x0052) register.
Section 5.0 describes the UTOPIA Interface in more detail.
ATM In
either passes or removes incoming Idle cells
either passes or removes incoming Unassigned cells
provides a counter per UTOPIA port for the total number of Idle/Unassigned/Filler cells with a valid HEC or
optionally the total number of User cells (24 bits/16 bit latched)
provides a counter per UTOPIA port for the total number of cells with wrong incoming HEC (24 bits/16 bit
latched)
provides a counter per UTOPIA port for the total number of cells handled (24 bits/16 bit latched)
provides counters for Parity errors

Reference
Note 1: This FIFO is the
TX UTOPIA FIFO when
the link is configured in
non-IMA Mode and it is the
TX LINK FIFO when it is
configured in IMA Mode
Note 2: In MT90222 groups
0,1,2,3 should be used.
